Mendelevium - Periodic Table of Videos

[steveo1274]

Why do scientist always have big non brushed hair? Am I the only person that notices these things?

[MrWooaa]

i wachted this as part of my chem homework. by the way, the scintist wtith the glasses would be a good canadate for the 12th doctor.

[SilentRinger]

ThE Professor reminds me Of an older version of Elliot Carver from "007 Tomorrow Never Dies".

LIKE IF YOU AGREE!!!!

[koopa322]

check out the clock at 1:41.

[alewis514]

I'm from poland and we drink lots of vodka. 0,5 liter bottle is "pół litra" or "halba" in colloquial terms and it's very very often used as gift or drinking unit. Emptying such a bottle yields around 0,3% BAC (this is heavily dependent on weight tho) and makes you really wasted.

[EvaPilot1]

@wspol624 I'll keep that in mind.

[loupax]

I usually wear jeans and t-shirts, but now I want a tie like that!

[Prismaglobe]

hah, great video. My chemistry teacher has the same clock and tie.

[TheItalianPerson]

i love that clock!

[genstian]

Actually it's 37.5% because it reacts better with the filters

[mahirharoon]

thanks, i have learnt nothing about mendelevium

[mahirharoon]

thanks, i have learn nothing about mendelevium

[MightyJustas]

As far as i know - mendelevium is some kind of element. uhmm, so vodka is called mendelevium?

[DannyFox06]

I think ima get myself a t-shirt with the periodic table on it.

[Burkieeee]

I don't know what I want more. The vodka or the clock.

[eskimofo89]

geek overload

[luigi90900]

Tablé!

[DerAnstifter]

Cool fun note that of водка used in so many experiments as a solvent.

[trppmdm]

One thing I want to say...

HE SAID NOTHING ABOUT THE ELEMENT!

Only for Mendeleev.

[shelteringshade]

He made up the whole table and they name after him an element with "practically zero use"...

[DeepAbsentia]

I think i'm the first to notice his face reactions, wich are almost identical from Dr. Strangelove. 1.40

[coolragazzo94]

how to say vodka is educational? say that is a good solvent in chemical reactions

[sirhonkalot]

Poor Lothar Meyer. He invented the periodic table at the same time as Mendelejew but all the credit for inventing it goes to Mendelejew.

[Alkinoos7]

Nice vodka, I'd like to keep one in my house to show it off sometimes...

[zeppelin812]

Oh. I thought my name write like Dmitry, whit "Y". Like in passport.

VODKA = POISON

[douro20]

@zeppelin812

You don't drink a lot of it...just a little in a small glass.

[zeppelin812]

@douro20 I don't drink vodka in general, because at me bad associations with it.

I'm from Russia.

[ChRIs23696]

hoping to go to nottingham uni in a couple of years :)

[PostRockIsAGenre]

Where can you buy that vodka? I want to get drunk... on science.

[genieieiop]

#OMG A PERIODIC TABLE CLOCK!!!!

[cardshifter]

Yay. I just watched my 118th video about the periodic table on this channel. I finished watching a video for every element on the periodic table. Thumbs up.

[iRant4u]

Russians and their vodka xD

[bandosgwds]

so does this mean you can go out and get some ethanol and water and have alcohol?

[Gopalissocoollike]

@bandosgwds ethanol is alcohol, its one kind of alcohol anyway

[natemcgraw]

@bandosgwds if you go out and get some ethanol you have alcohol no water needed

[manboobmanifesto]

What chemist doesn't have a handy bottle of vodka in his desk?

[harshrocsu]

Mendelf Vodka!!!

LMAO!

Chemistry tutors are drunk hard!!

[pyrosimple]

You have spoken more about Mendeleev than about Mendeleevium

[jdragon1012]

when they say that elements are poisonous, i dont know what they mean, what does the element do to make you die.

[BB1951]

@jdragon1012 I imagine when they say 'poisonous' they mean that the element is toxic and dangerous. If not handled properly. Hmm...

[jdragon1012]

@BB1951 i realize that but at the atomic level how does it kill one. but you must first understand what is life at the atmoic level. well i imagine life is a VERY complicated web of chemical reactions because we are made up of elements. theses chemical reaction recipricate and go in a cycle and that is our life. but a "poisonous" element is an element that wins a competition reaction with the body thus disrupting the cycle of chemical reactions that make us alive.

[kyungjinn]

You know a chemist is hard core when he's got a picture of Mendelev on his tie... lol.

[ButterflyNM14]

i lol'd!

[Vennificus]

@kyungjinn He has also got a periodic tie, umbrella, and mug

[aquarianbabe]

@kyungjinn the hair, the tie...this guy can't be STOPPED--he's a freaking rockstar!

[whydid666]

nice history lesson but kinda sad video i mean all we got out of it was that the most important chemist of our time was named after the most useless element, sides from Humans having no use for element 101 what are its properties, radioactivity, ect.

[lilwayne30001]

how does mendelevium look?

[Strideo1]

@lilwayne30001 More importantly how does mendelevium taste?

[killadonuts]

Anyone else notice his clock? Instead of numerals it has the symbols for Hydrogen through Magnesium

[Bloodscalpr]

haha i want his clock and his ties :P

[bfinn72591]

@killadonuts dude, nice call. thats a sweet clock

[DeltaPhi79]

One of the first videos for this account shows that.

[919664]

@killadonuts where did you see that clock ?

[killadonuts]

@919664 you gotta look carefully on the wall to HIS left up high

[Unclesamslair]

@killadonuts cesium atomic clock

[biolarulezderwelt]

@killadonuts epic WIN

[psr43]

@killadonuts my chemistry teacher has one too

[m4ps]

Vodka is closer to 38% actually. 40% was then used for tax reasons, being easier to work with.

[plottotakethemdown]

that guy has awesome ties.

[cplai]

Is it true that Vodka is pure alcohol solution in water? I didn't know that. What about the other impurities from the brewing process?

[CarnalDiafragma]

Yes it is true, it's usually distilled till about 95% ethanol and then diluted with water to about 40%, so it contains quite little impurities.

[bloodbath282]

Vorbis5,actually its lithium past nitrogen ;P

[pepsibookcat]

Scientists + late night in the lab = need vodka ;)

[PartVIII]

or pure ethanol =P

[KyuubiNaruto1337XD]

which is poisonous

[PartVIII]

then why am i not dead? you dont drink the pure ethanol, you mix it with beverages just like you do with vodka.

its much cheaper and doesnt dilute the cola too much.

[KyuubiNaruto1337XD]

pure ethanol is poisonous, when moonshiners make "moon Shine" the byproduct is ethanol which is poisonous which leads to blindness

you drink alcohol, ethanol above 1000ppm is poisonous

[PartVIII]

@ KyuubiNaruto1337XD im not sure if you even read what i wrote.

you should obviously add the ethanol to another beverage like soda. with vodka, you are diluting the beverage with unneeded water and therefore have a weak tasting drink.

pure ethanol will not make you go blind, you were thinking of methanol. methanol is a completely different molecule and is a byproduct of fermentation but can easily be boiled out of the solution due to a lower boiling point.

[KyuubiNaruto1337XD]

when fractional distillation doesn't fully remove the ethanol it becomes a byproduct

when ethanol is mixed in the drink such as vodka, its ppm goes way down to where you would die of drunk-ness before the ethanol even takes any effect on you.

the CDC has a report saying that ethanol is poisonous above 1000ppm

[gamingfan1989]

@KyuubiNaruto1337XD you are aware that ethanol is what makes you drunk, right?

[KyuubiNaruto1337XD]

are you aware that the only think that makes you drunk is the alcohol, thats why they call them alcoholic drinks.

[gamingfan1989]

@KyuubiNaruto1337XD ethanol is alcohol

[KyuubiNaruto1337XD]

ethanol and alcohol are 2 different chemicals in the alcohol family.

[tomoflore]

Alcohol isn't part of the alcohol family, it's the name for the family, any organic chemical with an OH functional group is an alcohol. It takes like 2 seconds to wikipedia this stuff, how can you get it so wrong?

[Stifflerino]

Nope, Dimitiri Mendeleve

[GuppyMister]

1:43 periodic table clock?

[JaksProductions]

yea cool

[Drag0nfoxx]

Yes, he actually talks about it in one of the videos.

[EnragedSephiroth]

You're right, that IS a sweet periodic clock. Leave it to the Russians to commend someone for their contribution to Vodka.

[shaftymcshifterson]

sweet fucking clock dude... periodic table clock... 1:45 behind his head

[Vorbis5]

Its 15 minutes past nitrogen

[NBCDateline]

Yes it is ^,^

[DIYsharkey]

Why does he have a bottle of vodka in his office? XD

[Sharkness77]

Because he likes to party

[Ilovecoffeex12]

Sometimes I come across people who I wish could live forever and this guy is one of them!

[pHzerodotcom]

You guys on periodicvideos are brilliant - I'm amazed at how you can make a boring element like Md interesting.

If I looked it up on wikipedia I could probably find its isotopes, its electronic structure, maybe its physical properties. But I'd never have known that you can get vodka labelled as "C2H5OH+H2O" or that the periodic table's called the mendeleev table in russia etc :)

[Gichnni]

lol periodic table tie!!

[ELFHUNTER50]

lol i always see that guy with his periodic table tie

[Roddyoneeye]

God! How I love good education!

[StormRisingOriginal]

This is at the low-end of education my friend. lol

[pccalhoun]

You are at the low-end in general my friend. lol

Seriously, you're a dick...

[jacraf]

Wow...Not only does he have a periodic table tie and umbrella, but he also has a periodic table vodka bottle as well!

Also look in the top left corner at around 1:30

[Airsofter1995]

He has a periodic table of desserts also :)

[gigaduck]

Keen observation..... thats awesome.

[zalencig]

Where the hell do I find that professor, and when can I shake his hand?

[blicblak]

University of Nottingham, England. Go there, either wait for him, or get into the school. Shake a hand for me too!

[zalencig]

Sweet! Thanks bro!

[blicblak]

Just to let you know, its gonna be extremely tough to get in there. Its expensive as hell, and its in England. You need to be uber smart

[cuteboymimmi]

what a useless element

[bedeone]

just like your comment ...

[InBloom10]

I want that tie.

[NatalieKateee]

I need that tie.

[zakyb1]

try thinkgeek!

[jbeer82]

Mendeleevium is a short lived Actinide has a half life from 0.9 ms to 51.5 days.

In solution the element possesses moderate stable dipositive and tripositive oxidation states which is characteristic to the Actinide. There has been no real known uses. Mendeleevium is produced by the bombardment of Einstinium with helium ions,Therefore Beta ray.

[liam7morris]

nice read of wikipedia

[th1nker21]

Doc you'r amazing ..oh and the tie you have are very nice...

[howe094]

ok, these videos are normally good, but seriously, i expected to actually hear him talk about mendelevium, not the history of Mendelev. They didn't mention anything about the chemistry of the element once.

[teojm37]

thats cause theres nothing much to talk about it

[widwarlock]

hei so i suppose he got vodka for irigation

throat irrigation.....very nice videos the kind a things youtubbe should only have

[Kaarel314]

He seems to have a really nice collection of ties. I would like to own some of those as well.

[legominifigure7]

(reply to the stupid comment of 12241a, see the 7 thumbs down below) ok, 1, you are an asshole, 2 it is useful in nuclear physics, and 3, it costs...hmm...about a million dollars a pound.

[bruenor82]

where do you get those ties Prof?

[CONNOR1225]

These videos are amazing....Because stupid people dont watch them then leave trivial comments.

[Gomka1000]

not always look up at 12241a's comment >:I

[ChocoPrincess116]

HAHA!!! I HEARD IT!

[qwAirGear]

Hmmm, vodka as the solvent. That's a useful idea, though let me say I'd think that the people doing that would get a slightly stronger kind; it's not that hard to get 80% here and I'd assume 50% almost anywhere, so...

[GlueStikkzz]

oh man, I love this guy, I want him to be my chem professor!!

[zetsu937]

that clock at 1:40 is awesome

[sy1234]

The clock is featured on an older video.. I can't remember which though..

[Woad25]

I bet this guy is just full of awesome stories like that :)

[Paxmax]

I have discovered that 60% of vodka is totally useless and has no significant impact when drinking it!!!

[Maarten26]

Wouldn't recommend omitting this 60% when drinking though ;)

[Paxmax]

Hahaa might be a little tinsy winsy harsh to drink it pure .. yes... =o)

But.. what if I want to add something else than water for 60%!!??

Hehe... the Limited Swedish Edition of Laphroaig(1988) is somewhere above 49% alco... mmm yummy.

[deezom]

haha, i almost jumped when mad scientist dude got up at 1:00. lmao

[rockstarmyles]

his hair means buisness

[KnightKiller1000]

Well I got water now all I need is either pure ethanol or impure to make me some good vodka!!!  Horray for SCIENCE!!!!

[penanceangel]

Also, because of it's purity, vodka is often used in infusions, where a particular natural flavor is added as an impurity to an alcoholic beverage, often by simply soaking the additive (like apples, spices,or peppers) over time.

[IncoherentRussian]

These videos have little information on the properties of the element and too much history.

[rochelimit55555]

that's why i like it, coz that kind of info is very hard to find in general encyclopedia

[Caehan]

That's true for elements with high proton number, but it is nice anyways. You didn't really expect them to show you seaborgium, did you?

[bariman89]

Interesting, i didnt know vodka is just ethanol and water, and i definitely did not know Mendeleev worked out the ratio for vodka.

Good work, keep it up

[adrastea99]

Every alcoholic drink is basically ethanol and water

[Mekill60]

What about pure ethanol?

[maekern]

There are also "impurities" other than ethanol and water, but since vodka is considered a neutral spirit, the goal is to make it as close to pure ethanol and water as possible. The way that, say whisky is different than vodka is entirely a result of impurities that are not distilled out. In whisky you want a lot of impurities, and in vodka you want very few.

[BartVanBockstaele]

That would very much depend on the type of vodka. Pertsovka, my favourite vodka, also contains red peppers although it could be argued that this is a negligible part of the liquid.

[Maarten26]

40% is a guideline not an exact proportion you get in distilling. The percentage is often much higher in the first stages of distilling. You obtain this this 40 % by either adding more water or a lower alcoholic vodka (often same source, later stage). Indeed alcoholic beverages are mainly water and ethanol, but that is simplifying. There are also a lot flavours that evaporate and condense in the process. If it was merely water and ethanol it would taste like rubbish. Trust me, I make this stuff.

[FerociousBoo]

wow, I didn't know that Mendeleev worked out the standards for vodka. Interesting facts

[johnclavis]

The story of Mendeleev is actually quite fascinating -- how he actually predicted the properties of some "eka"-elements!

Great video, as usual! Keep it up, and thanks very much!
