A Periodic Table Puzzler - Periodic Table of Videos

[SSJkiller]

The whole table is just a mess...

[vitorino807]

Element Ji 105.

[neveranythingtodoXD]

Element 105, as vitorino said, it's Ji on that periodic table, but now is Db, and 106, on that periodic table is Rf, but is now Sg. (I had to look at a periodic table though, so i suppose i cheated... took me about 5 minutes to find it out) :P

[mota900]

is carbons RAM not just 12? ...it says 12.01 i fought it was always taken to be 12 ?

[Aviatorsmith]

@mota900 It's not exactly 12.

[zombierobopirate]

@mota900 theres also carbon 13

[gwydiot]

i teach environmental safety, health, and cleanup. at the former school i worked for, we had a nice periodic table from a commercial lab on the wall, and i noticed that they had the symbols for Helium and Xenon both as He. i called the lab, and they were very embarrassed!

[TheBrickwallfilms]

elemement 108 is HS, not HN, and JI (105) is not an element. 106 is SG, not RF, which should be in 104. 105 should be DB, and lastly, 110 is UUN or DS

[koopashells21]

Jl

[ConnorHause]

First thing I thought: there is no J on the periodic table. So let's check for that. Not sure about Db though.

[witherspoon1995]

Db is element 105, Jl is not an element. 

[Superchickenman159]

Pause at 0:57, element 104 "Db" is supposed to be element 105.

[Warriorchamp1]

I think there was was only one hydrogen there should be two one at the beginning and one right after it on the other side

[wookidoo]

@Warriorchamp1 First element is hydrogen with the chemical symbol H. Second element is helium with the chemical symbol He,

[krisraps]

Im Now In University In baltic Country Latvia

Here is Much harder Jobs In Here Then Usa Or UK ..

And There is Changes And I Don`t nKnow MAYBE Mistakes !

But I Don`t Think SO

[ConnorXV]

I noticed two elements with different element symbols from to 1-110 I won't tell you which, all I'll say is Jillium and Hurnium.

[rolandas1985]

Everything is are situation. So condition is situation which we see. If another condition we can see much more another and new structure of this same elements. Den we can test mistakes. Need find more situation's.

[botonromos]

perhaps it is in the atomic weight of one element.

[botonromos]

@botonromos sorry, just saw the other comments, take no case on my comment and have a nice day ^^

[perraslocas]

110 Unn it should be Uun, i had to go through my periodic table, it took me like 2 hours

[BadBalloon]

White seems to mean that the element is only man made, never occurring in nature. But technetium and promethium are both found in nature.

[apophes82]

@BadBalloon You are right both elements occurring in nature although i thought untill today Tc is an exclusively synthetic element. But the white color marks the radioactive elements.

[BadBalloon]

@apophes82 But what about Uranium, actinium, polonium, all the otehr radioactive ones. They're in black. White starts with neptunium, which is generally regarded as the first exclusively man made element. If white meant radioactive, the viciously radioactive Francium would definitely be.

[TheFrozenGlaceon]

The only mistake i can see here, is the Unn. Shouldn't it be Uun according to the time it was printed?

[TheAsianCubanWhitey]

I ask my teachers Chem/Integ teachers and science teachers about Copernecium and C60, they dont even know! so im glad these videos shoe me these so i know a bit more then the teachers do.[ Even though they think im stupid for those things because they think i make it up, i tried showing them, but thehy wont let me.] Thanks for the videos!

[ChemPoke]

Dubnium should have atomic number 105 and Rutherfordium should be 104 with Seaborgium as 106

[cometeesta2010]

YOU, SEARCH IT!!!!!!!!!!!!!!!!

[RectumPilum]

What are the roman numerals and the letters after them (A or B) above the collumns used for? And why are thy placed like they are?

[RWBHere]

According to Wikipedia, Primo Levi lived July 31, 1919 – April 11, 1987, so 15 Maggio [15th May] isn't the 10th anniversary of his death. And, shouldn't '110 Unn' read '110 Uun'?

[imaball]

oxygens automic mass is incorrrreecctttttt!!!!1111111 jk idk. its rounded thougH? on here?

[ParkourJayy]

Hg is missing

[nickrupert]

There is a shitload wrong with this. 110 should be Uun (Ununnilium) not Unn (Unnilnilium), for example. Also Db (Dubnium) should be 105, not 104.

[nickrupert]

There is one mistake: 110 should be Uun, not Unn. The two changes are Jl -> Db and Hn->Hs.

[brhaosys]

1:00

Unn should be Uun

[AssemblerGuy]

Element 110 has symbol "Unn" -- according to the system for those three-letter provisional symbols, this should be Uun, U (for "un") means 1, and n (for "nil") means 0, so 1-1-0 should be "un-un-nil-ium", and have symbol Uun.

[nissimvas]

uun not unn

[periodicvideos]

@MACAO9991 True that these are now changed, but they were not really "mistakes" when the table was made! See the blog link I've put in the video information for a full explanation of the true mistake!

[xfragaming]

im in high school now and i really really love chemistry and you guys are my heroes dont stop making these awesome vids!

[periodicvideos]

@xfragaming thanks.. we've got no plans to stop just yet!

[alitavakoliwww]

@xfragaming i have the same feeling as you i am grade 10

[mrmagnetoman88]

Elements no 104-106 have been wrongly named. Element no 104 is rutherfordium, element no 105 is dubnium and element no 106 is seaborgium.

[Dracopol]

Easy. When an element is still unnamed, it is given a name made up of Latin numbers such as "nil" (0) and "Un" (1) to show the atomic number.

Observe atomic number 110. Formally by this system it should be Ununnilium (Uun) but they mistakenly printed it as Unn!

[mistergarth]

Shouldn't Lanthanum be in the Lanthanide series, and Actinium in the Actinide series?

[vevenaneathna]

Cs is shown as a solid?

[UkiSmileyFace]

Isn't dubnium supposed to be 105 instead of 104??

[halla369]

element nr 110 is named unn instead of Uun perhaps?

[Phacias]

@halla369 Your answer is correct.

[illogicstube]

@halla369 Si. Correct.

[ItsScienceBitch]

Its so obvious now, feeling pretty silly.

[opiumgland]

lol at the many dislexic and colorblind responders:

1) Hydrogen and Helium ARE a different color than the transition elements

2) Jl is an uppercase J followed by a lowercase L. There is no element Ji on that table.

[OscillatingRhythms]

@opiumgland You are one belligerent and ignorant fool. I think you'll find that you misspelled dyslexic. In Britain we call that irony - look it up in the dictionary, chump.

[Azner2254]

transactinide elements?

[AlexSh789]

@MACAO9991 Was I even talking to you?

[Intskyste]

If you're meaning the ordering of the elements then most printed periodic tables go out of date pretty quickly for various reasons anyway, so one from 1997 will have quite a few 'errors' looking at it today =P

-But yes, 110 would be Uun instead of Unn since the second digit is 1 not 0; un not nil =D

[YellowMagi]

If the prof can't see it, how can i see it?

[Softyx07]

found it! As a matter of fact: Unn would be the systematic name for element 100? wouldn't it? So it has to be Uun?

[periodicvideos]

See blog link under the video for information about the answer we were looking for!

[melekhthechanger88]

well Unn I think is Ds now after Darmstatium but thats the only thing I found find, whats the other one?

[Pazma1]

Ha, I've finally figured it out: it's shopped, you can tell by the shadows.

[dominic14061995]

Apart from hydrogen being in group 1 instead of in the middle and the naming problems in elements 104, 105, 106 and 108, i can't see anything wrong.

[T0mNZ]

@dominic14061995

Whats wrong with hydrogen being above group one? group is related to valency. Hydrogen has one valence electron just like sodium and potassium.

[dominic14061995]

@T0mNZ Actually it's okay. But some periodic tables place hydrogen isolated from the other elements since they say that hydrogen is not an alkali metal, so it doesn't belong to group 1. However, since it does have only one valence electron, it could be placed in this same group as well.

[melchior00625]

Ah, comments are screened. Okay.

I think it's element 110, what would eventually be called Darmstadtium-- specifically, the interim symbol. "Unn" (Un-nil-nil-ium) would imply element 100, or Fermium; the correct interim symbol would have been "Uun" (Un-un-nil-ium).

Further, fermium was discovered in the 1950s, while the IUPAC naming system was developed much later, so "Unn" should not exist as a chemical symbol. Well, maybe Uranium with N nitrogens...

[subarumitsubishi]

By the way, Unn would be element 100, Fm.

[melchior00625]

I think I see the error; hopefully I found the right answer.

[subarumitsubishi]

Element 110 at the time was spelled incorrectly. It's Uun not Unn.

[culwin]

104 is Rf...what the heck is "Jl"?

[EyItsKimron]

is it because on the table it doesn't show that caesium and francium are liquids at (or near) room temperature

[Jaleenaxx]

..I think i got it! =) Waiting for you to post the right answer ;)

[megs97216]

105 should be Db-Dubnium, 106 should be Sg-Seaborgium, 108 should be Hs-Hassium, 110 should be Ds-Damaladium. Uub gets moved to element 112. They are mising elements that had not beeen discovered in 1987. Its the same table with less elements.

[simpsonstewie]

lol took me 2mins

[CorrosiveNerds]

It's Elemtent Number 108, Its now called Hassium so Hs and in

the pt of Levi its still Hn for Hahnium.

[CorrosiveNerds]

Okay I found it , too

[jeebersjumpincryst]

@kawana87 YES!!! So would I. Thats a really good call, kawana87. btw, do u live in kawana waters, sunny coast...? J :-)

[forestlight5]

elements 57 & 89 should be located at the bottom

[applenaut]

Does it have to do with elements 104,105,106?

[jdk88888]

element 104 should be Rf (Rutherfordian), element 105 should be Db (Dubnium), and 106 should be Sg (Seaborgium). 108 should be Hs, not Hn, but Hn could still be Hassium somehow.

[ttwaylac]

Found it

[peasinacan]

...goddamn this guys hair is awesome!!

[skadogg22]

Element 111 is not there and element 106 is not Sg. That is my answer!

[BirdValiant]

It would seem that elements with white fonts are synthetic. Note that Francium and Astatine, both very radioactive, are shown in the normal black color denoting solids.

Both promethium and technetium are colored in white, so this periodic table implies that they are both synthetic elements. However, they are both present in the earth naturally, as they are produced as decay products from U-238. In fact, the mass of promethium in the earth's crust is probably 20 times that of astatine.

[trunkszetto]

that Wikipedia article sums up the "mistake" pretty well... but even before reading it I picked up on 105 right away. :)

[rjhrjh3]

The colours are wrong. Elements 13, 32, 51, 84 and all those underneath them should be a different colour. These are the "other metals".

A few elements have different symbols, but that could be due to the age of the table.

How to find the answer. Find a table and compare the two.

[SacValleyDweller]

*compares the table as-hung to the modern*

Got it!

[kcazzo69]

Mistake: it was created too large. "No periodic table shall be created larger than that which The Professor can wear on his person".

[Dazmaster75]

104-106 are the American proposed elements, and not the actual resolved names from the 39th IUPAC assembly

[jacksawild]

I don't see fire, earth, water, metal or wood... so that's five. Right?

[kobie1231]

And when are you going to reveal that answer? A week?

[kobie1231]

Oh, and I also see that actinium is in the wrong place! Is that it?

[theoneintheyellowhat]

I think I've got it  !

Can't wait to see the answer (perhaps in a new video with the story or history explaining why ? )

[kobie1231]

Dubnium is 105, right? It's 104 on there and 105 is something like JI and I don't know what JI is. Is that it? Or is there something that i'm missing...

[TheMrbunGee]

looks like something is wrong with elements 104 - 106. :\

[Amiga96]

Letters of elements that are differents

104 (Rf), 105 (Db), 106 (Sg), 108 (Hs), 110 (Ds)

Elements that are missing

111 (Rg) Roetgenium, 112 (Cp) Copernicium, 113 (Uut),

114 (Uuq), 115 (Uup), 116 (Uuh), 117 (Uus), 118 (Uuo)

The molar mass (masse molaire) of Lead (Pb, 82) is at 207,20 instead of 207,21

And all of the molar mass of the unstable element are differents, but that's quite a subjective value anyway.

[alexdenton02]

Ok here is my answer. The amphoteric line shouldn't be drawn down between 84/85 assuming Astatine is a metalloid and not a halogen. I know Aluminium is on the line, but it is always explained that it is a special case. In this situation the line shouldn't be drawn down the 84/85.

[gibsonbaud1]

Ahhhhh!!!! I just figured it out... 110 is suppose to be Uun, not Unn.

[gibsonbaud1]

Column 12 (Starts with Zinc) is suppose to be in the transition metals group.

[LastXzIII]

The white part starting from the element Db(104 which is now Rutherfordium) to element 108.

[Jethroguitarist]

Element 105 in this periodic table is JI which stands for the Joint Institute for Nuclear Research in Dubna, Russia. The element was later named after Dubna which is now the symbol Db for Dubnium

[Ceevro]

Element 105, Joliotnium, was resolved to be named Dubnium in 1997.

[Ceevro]

Element 105, Joliotnium, was resolved to be named Dubnium in 1997.

[dimitri81523]

104 Rf, 105 Db, 106 Sg, 108 Hs, 110 Ds, 111 Rg, 112 Cn

[skeebert]

its missing skrotomite.

[ItsRainingDonkeys]

whats? Co . lol

[beerengr]

Aside from the element naming controversy, there is that one small "binary" error.

[DuskY1991]

Hmm, think I got them!

[neddy17]

i found 4 things which are different for the time, but not mistakes

[pressuredrop77]

Uhh, 110 Unn should be 110 Uun?

[snoplau]

Not a chemisrty buff or anything but i think i may have it!

[nhojmabon]

Haha found it :)

[okuma0kuma]

been long time since ive actually looked on a periodic table about 20 years but element 104 is called Rf but one video it is labelled 106 !

i gues that element id it replaced is a very active and dangerous element if wrongly mixed by others !

[jHotmetala]

The date of the table, that is what is wrong.

[qjzk]

The mistake is the use of the symbol Unn for Element 110. The systematic name for Element 110 was Ununnilium, which has the symbol Uun. Unn (Unnilnilium) would correspond to Element 100, which is Fermium.

Take a look at the Wikipedia article for "Systematic_element_name"

[charlesthegodfather]

elements 104-106

[CHESEPOWER]

I can't seem to find it, i have been looking for half hour. But i won't give up!

[cameron1004]

Is it that element 110, ununnilium, should have the symbol Uun, not Unn?

[atomictesting]

It is my opinion that the error to which this video refers is that element 103 has a higher mass than element 104. While I understand that this is entirely possible for individual species of unstable elements, it's pretty silly to pick ones that give the wrong impression of their placement on the table as this one does.

[jhonbus]

Also, they picked Rutherfordium instead of Seaborgium.

[dajwilkinson]

Yes, just the "one"... (name changes excepted)

[JediOrSith89]

At the bottom right corner of the periodic table it says 1997. sooo according to Wiki the names of the elements 104-109 should have been as IUPAC agreed in 1997 at Geneva, Rutherfordium, Dubnium, Seaborgium, Borhium, Hassium, Meitnerium! But still I'm not sure....

[l3oss2u]

found it. 

[jhonbus]

Element 110 (now called Darmstadtium) should be on a Periodic Table of this era as Uun, but this table has Unn! No such thing.

[chemiealex]

I think I found it :)

But I look forward to your answer!! :)

[Kendrana]

Another weigth related mistake. Germanium is 72.64g/mol on my table and on Wiki's one, but on that table it's 72.61g/mol.

[drax325]

I hope it is not the italian.

[CroThunder]

Is it the element 110 Ununnilium?

right is Uun and on this table is Unn

[Kendrana]

Heh, I found a mistake on my periodic table at home, it shows zinc as 65.41g/mol but it's actually 65.38g/mol (according to Wikipedia). The subject table shows it at 65.39g/mol. Is that a [the] mistake?

[greeneyedgeek]

Hassium??

[rabbitsib]

The synthetics got me confused

[chizzy555]

nope

[4jonah]

Element 104 SHOULD be labeled Rf, but on the table its Db (which in actuality is 106. So they are actually reversed. And I don't know what the Ji is in the position of 105. Maybe thats the mistake too.

[mortarbr]

Rf is element 104, in this table it is 106, the mistake occurred because between 1994 and 1997 Rutherfordium really was the element 106, that happened because IUPAC had a rule that no element can be named after a living person (Glenn T. Seaborg(element 106 is Seaborgium)), but Einsteinium was named during Albert Einstein's life. In 1997, as part of a compromise involving elements 104 to 108, the name seaborgium for element 106 was recognized internationally.

[Tiggercobalt]

FRUSTRATION.

Someone inbox me the answer.

[opiumgland]

Interesting that a Latin typo would be made in Italy.

[courtkneepee]

i think it has something to do with element 105... i'm not sure though.

[ToonBowserJr]

Elements 104-108 are in the incorrect order. Seaborgium is missing, and Jl is no longer on modern tables.

[Kabukita]

The mistake is... that there is no mistake! Did I win?

[JediOrSith89]

there are differences with the atomic weight between now and then... but I doubt it as a mistake rather than tecnological precision.

[JakeKaje]

got it.

[skBundy]

i would say that

1: Oxygen mass is not 16.. is 15.99924

2. Tecnecium mass is rather 99 than 97

3. Astatine is highly unstable, but it says it is not

**and also a question.. Galium and/or Caesium(/Francium) are socalled as Liquds in many modern tables. Aren't they?**

[kanjitard]

My brain hurts

[kanjitard]

Ununnilium should have the symbol Uun not Uun

[ajhurliman]

Just to the right of Actinide (not the Actinide series, but under the transitional metals) my periodic table reads Rf Db Sg Bh Hs Mt Ds which represent elements 104-110. That one lists Db Jl Rf Bh Hn Mt Unn

[kaglioster]

From '97 the IUPAC name for element 108 is Hassium (Hs), before the name was hahnium (Hn).

The themporary name of element 110 Ununnilium (Unn) was officialy changed in Darmstadtium (Ds) in 2003.

PLUS

111 Roentgenium and 112 Copernicium are missing :)

[MrYfe]

Number through 110 is all messed up; on the board it lists the elements in this order:

Db, Jl, Rf, Bh, Hn, Mt, Unn.

Today they're listed:

Rf, Db, Sg, Bh, Hs, Mt, Ds.

Even if the elements have changed names since 1997 (because of the dispute), the abbreviation "unn" should be "Uun" as the letters stand for Un and Nil, being one and zero in latin, as in "one one zero": ununnillium (now darmstadtium).

[nzstato]

Hassium (element 108) was given the designation Hs in 1997, during this print Hn was accepted by IUPAC. IUPAC94 had Db as 104, JI as 105 and Rf as 106, this was changed in 1997 to Rf, Db and Sg in 1997. The big mistake however is that Lanthanum (57) and Actinium (89) are not listed in the Lanthanoid and Actinoid series where they should be but in the main block of the periodic table.

Am I right?

[NAMLegolas]

I found the 2 renamed elements right away... other than that I failed to spot the error :( Please forgive me...

[theshiz0]

Is it missing Rutherfordium (Rf) as element 104?

[mr0myster]

I thought I found it and then I checked out wiki and it turned out it's acceptable.

But now I think I found it for real...

[Muscleduck]

I give up :P I tried looking at the masses but most are right, some differ 0.01 or 0.02 with my periodic table (which is at least 5 years old itself).

The things I found with names are these:

105: Jl? --> Db (Dubnium)

106: Rf --> Sg (Seaborgium)

108: Hn --> Hs (Hassium, this can be the mistake, a typing error).

110: Unn --> Ds (Darmstadtium)

And ofc 111 and 112 which are recent discoveries.

[MrYfe]

Number through 110 is all messed up; on the board it lists the elements in this order:

Db, Jl, Rf, Bh, Hn, Mt, Unn.

Today they're listed:

Rf, Db, Sg, Bh, Hs, Mt, Ds.

Even if the elements have changed names since 1997, the abbreviation "unn" should be "Uun" as the letters stand for Un and Nil, being one and zero in latin, as in "one one zero": ununnillium (now darmstadtium).

[Kendrana]

@periodicvideos @Shalaiyn being on Twitter ofcourse.

[Merdam9]

110th element is not Unn it is Uun

[Kendrana]

@Periodicvideos Could you @Shalaiyn me or message me on Youtube if you know what the white lettering means? It can't be radioactive since elements like Radon are radioactive and arn't white, and it can't be synthetic because Tecnecium (Tc) is white and Tc comes from decay.

Which brings me to the thought, is it that there's elements which are previously thought to be synthetic which are actually radioactive or they made a mistake with the colouring then?

Hopefully you know what the white means.:p

[VideoJargon]

Elements 104 and 106. Today, they are named Rutherfordium and Seaborgium respectively.

[cardshifter]

I looked at the Transactinides first for the unnamed elements. It was easy.

[cardshifter]

Element 110 say's Unn. It should be Uun. U-1, u-1, n-0

[KzrrainzYes]

Is that the atomic numbers with parentheses around them have decimals?

[Tomo123OMG]

i spotted the mistakes in nanoseconds.... yes yes, Indeed flourine is in the wrong place, ah yes, pip pip, ta ra! Oooh the archers is on!

[soulfirexz]

Hahnium, and Joliotium!

[homousios]

if the Professor is stumped, what chance is there for us lesser mortals?But I will try. Thanks

[ummacles]

Hints:

How many elements have J in their symbol?

What is element "Unq" now know as?

[superdau]

Jl? I've never seen this symbol on a periodic table. And now that I look at the table, Rf and Db are mixed up, Sg is missing and Hn is called Hs. Which after further reading seems all correct for it's time. Is there another error?

[UniversePirate]

If the colours represent the blocks of the table, why aren't the alcalyne metals , alcalyne earth metals, hydrogen and helium the same color? Is it considered a mistake?

[andyroo24601]

Element 110 should be Uun, not Unn :)

[Draxis32]

There's an Element named as JI, wich is completely absurd since element naming is either a capital letter or a capital followed by a minuscule one, this element 105 now its named as Dubnium.

Also the element Telurium the letter I looks like the I from Iodine wich could lead to misunderstanding of wich one is the capital word.

[BYMYSYD]

i didn't know that  some elements changed names

[Draxis32]

There's an Element named as JI, wich is completely absurd since element naming is either a capital letter or a capital followed by a minuscule one, this element 105 now its named as Dubnium.

[drosprey]

Elements 104 to 106 are miss named but I can't find the mistake you are looking for
