Gold (version 1) - Periodic Table of Videos

[smartass250]

gold is great at reflacting info red light if you what some thing to last gold is non crosive.gold may be lorge enof to absorb some neutrons and there lots of gold componds.and yet a tv networe that actauly calls them selves mass shit natoinal bull crap sais it its yousless in a post apoceliptic society

[deadgamer42]

the scrolling screen saver says "The professor is a fuckin pimp" or this jus might be an opinion. Nah, he's a fuckin pimp

[ChaosButterfly8]

Is it possible that they are manufacturing gold Au ๏ in nuclear reactors and the whole nuclear power as green energy is a front?

[NANOFORGE]

Nuclear Fusion could be used to make Gold but it will be very difficult.

[Alubrab]

How does Mercury react  with Gold ??

[kitty6837]

@Alubrab I believe that mercury will react with gold by penetrating the oxide layer of gold and penetrate the structural integrity of it, sort of like how it reacts with aluminum. However I could be very wrong. I am new at this sort of chemistry, so please forgive me if i could be wrong.

[xanshriekal]

@kitty6837 You're forgiven. Gold doesn't have an oxide layer so the mercury reacts with the gold on the surface and then the amalgam allows the mercury to get into the interior of the metal. The reaction is similar to that of mercury and aluminum, but the resulting amalgam doesn't flake away like aluminum does. It just turns into a light silvery metal that doesn't look like gold.

[ArtypNk]

If only I could harvest distant solar cores.... 

[FusionNinjin]

hmm i need to make a particle accelarator so i can make gold and get rich $.$

[gaswerti]

i don't know what particle accelerator i'm talking about but it can make i think 1 million atoms of gold per hour but it would still take about 50 years to get 1 gram of gold so he is really speaking the truth that u can't get rich if u make gold atoms...

[9hello123]

@gaswerti at one million atoms of gold per hour it would take 8.7 years to get 1 gram of gold, not 50.

[gaswerti]

@9hello123 oh... well doesn't really change things because it's still very little gold in a long time :D

[NickyBasrikatte]

@gaswerti Calculations are as follows :- 1 gram of gold has (Avogadro's Number) / (Atomic Mass) atoms --call it (A). In 1 year, (365.25 x 24) x 1 million atoms produced -- call it (B). No. of years required = (A) / (B) = 348,770,000,000 years !!!

[NickyBasrikatte]

@gaswerti You're way off the mark, dude ! At one million atoms per hour, it would take not 8.7, not even 50, but 348,770,000,000 years, i.e., about 350 billion years to make 1 gram of gold.

[dradeel]

So it's 1.17 grams of grade 1 gold, which I assume means that it's what they call .999 gold (99.9% purity) when you wish to buy gold. With today's gold price, that little gold wire would have the value of 31.5 GBP, which is quite substantially more than 10 GBP :)

[derickhaywood]

"gold doesn't react with anything at all".... " i don't wear my wedding ring because i'm afraid it might react with mercury" bullshit meter is hitting max lvls

[dradeel]

@derickhaywood You shouldn't take "gold doesn't react with anything at all" as an absolute. It's a matter of speech regarding the general tendency of gold. There are very few things that will react with gold and ruin the gold. Mercury would "only" tarnish the gold by creating amalgams and make it silvery in color, which would ruin the aesthetics of a gold ring, but not dissolve or ruin the gold ring itself. You can reverse it by boiling the mercury out of the ring, which doesn't harm the gold :)

[STEVEGET]

@derickhaywood Mercury coats it and tough to get off.

[dwip57]

@derickhaywood remember budd... there is only one rule in all sciences... that there is no rule... its like the noble gases NEVER react with anything... but most of them react with Flourine. So please dont take the words out of their mouths literally and try to understand what they mean... :)

[noname7913]

I would mention the important use in computer components such as CPU's. The fact it's not reactive to much except royal water even when very hot allows for thin wires that won't wear out quickly. Gold connects the semiconductor to it's package in a process called wire bonding. In other components the gold may coat contacts to protect them and ensure good conductivity.

[mynameisdarthtater]

Gold can react with tellurium. Don't ask me how I know that.

[Harisdoubled]

@mynameisdarthtater how do you know that? XD

[mynameisdarthtater]

@Harisdoubled a book actually. a pretty awesome one i just read called "The Disappearing Spoon." its about chemistry but its still awesome.

also, the title is a reference to a neat little prank you can pull with gallium, which looks like aluminum but melts at 84 degrees Fahrenheit. So if you cast it into spoons then invite people over for soup, coffee, etc...

well, you get the idea

PS- gold also reacts with silver

[alex49carson]

ad is about gold

[johnmacward]

Why is Gold so rare on earth?

[ThrowingItAway]

@johnmacward one theory is that gold is so dense that it sunk to the earths core when the earth was forming.

[johnmacward]

@ThrowingItAway Ah, interesting, so it's probably mixed up ferociously in the hot soup below us. The reason I asked was that more atomically denser metals like the radioactive ones (Uranium for example) "seem" to be much more common than gold even though they're way more complex to explode into existence.

[ThrowingItAway]

@johnmacward uranium was most likely put on earth after it cooled from metors and other space junk

[EPICGUYDUDE]

"doesnt react with anything" then what about "auric acid" and "aurous acid"?

[1993gandy]

if it goes silver then you can sell it as platinum ;)

[dooovde]

Crazy haired guy says he doesn't wear his ring cause it might react with mercury. Then other dude comes on and says that gold is inearth and doesn't react with anything at all. Bit confusing that.

[pawningcity]

@dooovde gold does not react with mergury, it 'absorbs' mercury and it gets black in colour, its called amalgamation..

[smzig]

@dooovde Gold reacts with some things but when it comes to the chemicals an average person would come in contact every day, there's nothing it would react with. But if you're a chemist, there are some nasty things that can react with gold. For instance, Aqua Regia, a mixture of hydrochloric acid and nitric acid, can dissolve gold.

[1RadicalOne]

In the culture I come from, jewelery is conventionally made from copper and/or titanium. ;)

[kovertopz]

@ 0:08

That's what she said.

[misterflip20]

ok...how the hell did Rutherford make gold foil 400 atoms in width?!

[republic280]

gold is cool

[0Sebek0]

My teacher says that gold is a highly oxidizing agent, just because is the metal with strongest electronegativity, but I don't think there could be a compound with reduced gold.

Wath do you think about his bullshit...

[Slic3R1]

your teacher is an idiot

[skuul666]

there are actually compunds know where gold has oxidation state of -1, so called aurides.

caesium auride for example, CsAu, is made up of Cs+ and Au-

[0Sebek0]

wow yes, I should investigate more often when I hear about rare things, but yes in chemistry everything is posible, even compounds with an alkaly metal as the anion, the one I know is Na+ (NaL)- where L is a cyptant agent, something like a crown ether

[darksideofthebrick13]

Au=Aurium?

[skuul666]

no, Au = Aurum, its Latin name

[darksideofthebrick13]

no i?

[skuul666]

No, just aurum

There are also a few other elements with just the -um suffix:

-silver = Ag = argentum

-copper = Cu = cuprum

-mercury = Hg = hydrargyrum

-lead = Pb = plumbum

-tin = Sn = stannum

-iron = Fe = ferrum

[darksideofthebrick13]

o. thats cool. hydragyrum sounds cool

[darksideofthebrick13]

or aluminum?

[skuul666]

yeah i guess, although both aluminum and aluminium are accepted names

[darksideofthebrick13]

i see...

[ButterflyNM14]

nice...

[matoy77]

In diamond, Carbon atoms arranged in a crystal structure. Diamond is formed when high carbon magma slowly cools allowing the atoms to be arranged in this certain structure.

[HairLikeCottonCandy]

isn't pressure also important?

[ShervinGetOffMee]

what atoms make up a diamond?

[dabadeedabadie001]

Carbon atoms.......nothin else

[eutectics]

welllll, there could be some nitrogen in there (yellow diamonds) or boron (blue) or hydrogen (Purple i think) but these are in trace amounts so, yeah, you're kind of right.

[dabadeedabadie001]

well what i was referring to was pure diamond

[Supish16]

carbon

[TheKimzon]

carbon but really a diamond is a peace of coal put under xtrem heat and pressure

[HairLikeCottonCandy]

could you do it with graphite?

[KingArt777]

what is ten pounds in us money

[lastlanding]

about 16 US dollars

[Jonnonation]

He said pence in the video by the way so more like 16 c

[MagicPup69]

ah k thanks man

[BfeoAdmin]

Inertion refers to chemical reaction. While gold dissolves in mercury, it doesn't chemically react, and is thus still an inert substance.

[MagicPup69]

if gold is inert... then Mr. professor is a fuckwit because it could react with mercury. hes just not married

[BfeoAdmin]

Gold dissolves in mercury, forming amalgam alloys, but does not react with it.

[Gumbypotty]

White gold is a stupid alloy for jewelry. White gold jewelry looks boring, so it's plated with other metals - completely hiding the gold alloy!

[Airsofter1995]

gold is boring... ima buy a platinum wedding ring :P

[Drag0nfoxx]

Get a Uranium wedding ring.

[ValiantArrow]

Presumably, as many men as women wear it...

[mxy2kaxl]

there is other metals more expensive than gold

[360fatcats]

Platinum

[TheNewTwinkieLord]

how much is ten pounds in american

[SOTBS]

Currently, about $16, $17

[TheNewTwinkieLord]

thanks

[noah112234]

one word.....ideer...

[sabawshey]

if gold is so abundant why is it so expensive?50th comment

[RandomDota]

Because IT VERY shiny. as it is very unreactive just like noble gases, as well as in nature platium, gold and sliver in nature are found uncombine with other elements E.g (it can be with copper but not combined just with copper and gold seperate).. but its rare, its not THAT abundant i think.

[philman210]

He tells you in the video. It's expensive mostly because its unreactive. I'm on the sure side that just a small bit of the value came from the fact that people think its pretty(not totally sure about that).

[frozencanadian]

becuase there is a very high demand for gold due to its uses to counter the supplies. Demand and supply 101.

[dradeel]

I think it's because gold, like diamonds, 1) lasts forever. It doesn't react with anything (allthough dissolvable in mercury)... a quality people appreciates :) 2) Everyone thinks it's pretty. 3) There is a fairly fixed amount of gold being mined, so the price stays fairly high. It could probably get cheaper if they mined a lot more of it, but then they would earn less and it would be a waste, and also 4) it's not thaaat abundant. Only more abundant than many other heavy metals. ;)

[gamefrk2005]

Gold is expensive because the government controls how much can and can not be released to the public as well as others hording it

[penitent2401]

gold is used as a universal currency. nations always have a hoard of gold as a cash reserve, especially for trading with other countries since it's value is universal.

only some of the total gold minned actually go into jewlery, alot goes in industrial areas (computer chips, heat resistance foil...)

[juggliac]

yeah, alot of gold is used in many vastly different areas(i.e. entertainment, industry and astronautics) It is used on rockets to protect from solar radiation, becauser somehow it has unique properties with absorbing radiation, probably due to its very high density.

[mxy2kaxl]

i agree with u .. also there is other metals more expensive than gold

[RectumPilum]

Copper is one of the most expensive... that's about all i know about metals, except for some facts about unununium and plutonium =]

[blueduderanch]

@mxy2kaxl many are more expensive, platinum, francium, caesium, and astatine is the rarest. they are all very expensive.

[1011010]

I have to use that excuse when I get married. "Honey, I can't wear a ring because I'm afraid it will come into contact with mercury and go silver and not look nice." :D

[dreamofthemirrors]

Imagine taking 2 protons out Lead!

[Draxis32]

Yeah, but uuuh....either fission or fusion reactions to obtain gold, would turn them into Radioactive Gold isotopes more likely.

[juggliac]

fission yes, fusion though, no.

[Draxis32]

Not the Fusion that we can do. I'm talking about those dying giant stars, their tremendous gravity force, made heavier elements than iron that we have here these days.

But, you're saying that fusion does not produce radioactive elements/isotopes?

Cause i dont have any better explanation on how Uranium is in this planet, he just had to be produced from this stars.

[juggliac]

I thought you meant our controlled fusion. The reason Uranium is created radioactive however is because all of its isotopes are radioactive, but then again star fusion is totally random when coming to isotopes, you can get stable or radioactive regularly.

[andrebrannan1953]

Is this a new version I thought there was one which explained what white and red gold where.

[Noregi]

imagine sending in atoms and building a substance atom by atom, Not bery profitable, but could be very interesting.

[Myself0101]

this video was posted on my birthday...coincidence?

[porkypker27]

How many protons and neutrons does gold have?

[BirdValiant]

79 protons, 118 neutrons

[porkypker27]

thx

[BirdValiant]

I hope you didn't need that information quickly... :P

[porkypker27]

lol i did but i figured out long time ago O.o

[tybo09]

Random question: Why is it that most (if not all) catalysts are made of precious (and expensive) metals like platinum, gold, etc?

Is it because the un-reactive nature that makes them good catalysts also makes them fairly valuable or is it just pure chance that it worked out this way?

[tomandjj]

no there are still a lot of catalysts that are very cheap. I mean just about anything could be a catalyst it depends on the reaction you are doing. it is just chance that because gold and platinum are very inert that they can nearly only be used as a catalysts while other catalysts may also serve as parts in chemical reactions so you are more familiar with them being in chemical processes instead of catalyzing them.

[rekinu5]

omg soooo thin wire, wtf , i can hardly see it :D:D:D:D

[vmelkon]

Metals such as Platinum have a bp of 4530C. Certain metaloids have high bp as well. Can anyone tell me how these bp have been determined? Someone really heated them to such high temperatures and visually observed them?

[12241a]

trying to make gold from lead would make you bankrupt because you have to but so much technology and it would gost you billion just to make about a quarter size of gold so youd have better luck with just buying pure gold than makeing it silly

[jk3us]

He sounds like Ron Paul :)

[pedrotime]

i love gold :)

[WhatdoIdoforauser]

Perhaps he was afraid of accidentally dropping it in Aqua regia? Anyways... this video cleared up quite a bit for me as I was always fascinated by alchemy and like, always wondering if you could possibly change the element of an atom by introducing protons or electrons to it. So... at least now I know its plausible.

[ltt1213]

hes a liar hes not afraid that mercury will react hes just single =)lol im jk

[REYDOW]

na its to pick up chicks at the disco

[F3ARMUFFS]

That fro is pretty attractive.

[theguycalledchris]

Hey has anyone noticed that the screensaver on Fluffy Hair's computer is moving between TWO monitors that are next to each other with almost perfect timing?

[emt89]

yah, you can set it up so 2 computer screens turn into one screen. it is a very common thing to do. so you have 4,5 + computer screen and only one mouse... or whatever haha

[painnagonynmisery]

my teacher has a computer like that at first i was amazed but when i used it eventually it got annoying

[aopdjasldksa]

Why would it get annoying... You can have one side dedicated to a task while the other idle, playing a movie, or even another task. I don't understand why you would consider dual screen annoying...

[prisoner1138]

It's probably one computer with 2 monitors, not uncommon these days.

[desidreams19]

YES.

I JUST DID, AND I WAS LIKE WHOOOAHH

i'm such a weirdo.

[JUNIORROTAX55]

they said gold was inert but they also said that it is good for making rings because it doesn't oxidize for many years!

[JasoniumGH]

uhh so?

[add1c7i0n]

many years meaning longer than humans have even been around.........

[JUNIORROTAX55]

still not inert.

[GonGel]

yeah heavy metal ^^

[Mekill60]

So, if I made an electrolysis expirement, and used gold on both positive and negative ends, there would be no reaction with the metals whatsoever? (Other than releasing Hydrogen and Oxygen)

[redrightbear]

i lyke munie.

[danielbell12345]

at the end, did the professor guy say "there are better ways than making dope"?

[harrisonkk]

He says, "If you want to be rich, there are better ways than trying to make gold."

[rtsjoe]

rofl

[ZellCendo]

Gold is a Very Un-Reactive Metal and there has not been any Recorded cases where it has become Gold (...) but like he said as a chemist he doesnt wear a ring as it might react with Mercury all thats meant by that is that Mercury is a Liquid Metal and if was to touch the gold would actually Coat it and thou not Really form a new Compound it would be Extremly Hard to Remove.

Also there is a Case that Lead was Turn to Gold but Cost more than the Gold they recieved was Worth

[JeremyBechen]

Right, Gold and Mercury will NOT make a new compound. They make an 'amalgam'. That is, Mercury "mixed" with another metal or alloy. It just so happens that Gold and Mercury make this gold-mercury amalgam pretty well on contact with eachother. I've had friends who accidentally touched their rings with Mercury, and thus it turned into the silver-colored amalgam. I don't think it can be fixed, at least not easily.

BTW, there is no way (without VERY MANY nuclear reactions) to turn lead to gold.

[ZellCendo]

yes i know thats what I Said:

Mercury is a Liquid Metal and if was to touch the gold would actually Coat it and thou not Really form a new Compound it would be Extremly Hard to Remove.

basically in short, it'll cover it, not making a compound and be hard to get off,

also yes there has been a lead to gold case, they just wanted to see if it was possible which it was thou it cost so much to creat enough power to create the reaction the cost is not profitable

[Toxie207]

He said that Gold is "rather unreactive". Can/does Gold react with anything? Are there any known compounds containing Au atoms?

[Chumkil]

Yes, there are even medications that use Gold. Flourine will react with nearly everything - including Helium (under very specific circumstances). So that will react with Gold.

[Toxie207]

So would that be called Gold Fluoride?

[halori]

hmm... Aqua regia will just dissolve gold.

(right?? )

[vmelkon]

Yes, I think aqua regia is nitric and sulfuric acid. It would form gold nitrate and gold sulfate. Then you can dry the suff and heat the salts and it would decompose and you get gold powder.

[ayerodger]

it's not working!!
