Phosphorus (version 1) - Periodic Table of Videos

[test123ok]

nice Tie, Professor !

[NANOFORGE]

Was'nt phosphorus once used in incendairy ammunition?.

[macvegard]

@NANOFORGE

im pretty sure its still used in tracer ammunition or "tracers" to make a tail behind them, so the shooter can see and correct where the rounds are going. its loaded at an interval, so some normal rounds and then an incendary round to correct the the aim. it might also be loaded at the end of a magazine to tell the shooter that the gun is almost empty. check wikipedia for tracer ammunition.

i havent heard of it beiing used in incendary ammunition, but it has been used in other inc

[NANOFORGE]

@macvegard I read somewhere that phosphorus was used in incendariy grenades and rockest ect like you mentioned before the second world war, nowadays incendairy muntions are banned due to be being inhumane.

[macvegard]

@NANOFORGE sorry ran out of space,

i might be wrong, but i havent heard of it being used in any incendary amunition, but it has been used in other incendary weapons, like bombs, shells, and i think it has been used in some incendary grenades.

[PowderedAsh]

Used in thermobaric hand grenades, is white phosphorus 

[cokopoofe]

Wow. So there really is a possibility that I'll explode... nice to know. Add it to the list of how many ways there are for humans to die...

[IamMasivers95]

i love chemistry so much.. i know pretty much everything from the proton,neutron, isotopes, valence electrons,halogen and many more.. but sadly i pretty much weak on the calculations.. :(

[HayaJi]

Hello, really silly question, if P reacts easily with Oxygen, how come it can be kept in H2O and it doesn't react with the O in it?

Thank you for your time

[DANGJOS]

@HayaJi well for one thing, water tends to react with reactive metals, now phosphorus with phosphorus being a nonmetal, it has nothing it needs from water. reactive metals likesodium give up and electron to split water into hydrogen and hydroxide forming sodium hydroxide but phosphorus has electrons to gain not lose.

[macvegard]

@HayaJi

i am not a professional chemist, but i think it ts because the Hydrogen in the water has got a stronger bond to the Oxygen in the water than the phosphorous would, hence, it won't react.

and no, it is not a silly question, we learn from asking questions! :)

i just noticed, after writing all this, that DANGJOS has already answered your question, but i think my answer is not entireley uncorrect, and a heck of a lot easyer to understand :) shoot me if i'm wrong!

[wookidoo]

Did Pete just say carbon disulfide is organic?

[Zachdudeio2]

Just a comment, pure phosphorus is NOT found in match heads, rather it is found on the striker side of the matchbox. Just a heads up for those of you who collect that sort of thing, like me.

[grandexandi]

whats up with the crooked camera when the old dude is talking? is he THAT bent?

[GRAHAMAUS]

I found the claim about ATP so astonishing I looked it up - and it's true! You really do get through that much ATP a day. Wow!

[oldnick787]

hey whats phosphorus state of matter?

[JesusHChrist2000]

@oldnick787

SOLID

[oldnick787]

@JesusHChrist2000 thanks!

[loserofnothing]

that didnt look like a p -.-

[Nerusai]

Useful video

[TitanREW]

by producing inough phosphorous in my body (1lb) i use my inner Chi to collect it into my feast, then i can have an Explosive falcon punch.

[AllAtheism]

Well, the "non-safety" matches don't really contain red phosphorus or phosphorus of any kind but a phosphorus compound, tetraphosphorus trisulfide P4S3.

[FrostyByte]

The Prof has a Periodic table tie on :D

[jimday666]

@FrostyByte and a cup too

[UncleKennybobs]

Carbon disulphide eh? I must remember that one.

Must. Get. Chemistry. Kit.

[TheDoctorV2point0]

long while ago they had white phosphorus tipped bullets, would burn inside someones skin and caused massive pain.

[LilMissP1992]

Hey, that afro guy has a periodic table tie! Cool!

[rigby0105]

tht fellas hair is fukin quality, thinks he is proper ghetto lmao

[EeRrIiCcRam]

3:13 - 3:15

[multicow21]

so it is shaped like pyramid with 4 atoms but i though t its atomic number was 15

[brenoakiy]

the atomic number is the number of protons of an atom, so phosphorus has 15 protons in each ATOM

the MOLECULE of white phosphorus contains 4 atoms

[Vennificus]

@multicow21 atomic number 15 but the shape of the molecule is a pyramid, because it's made of four phosphorous atoms

[uut0]

i once got the powder from lotsa match tips and put that in a tube with some stuff in the top and ligthed it :D that gave a nice flame ftw

[SoldatSolutrea]

Phosphorus is the element of the gods.

[Digephil]

are the white tips on strike anywhere matches white phosphorous?

[pwn0grapher]

@guiy16 energy is released from ATP by breaking the bonds between oxygen and phosphorous atoms, so i would think it has everything to do with elemental phosphorous due to it's chemical properties.

[quickdud0rz]

I think it looks very much like a p. Cool afro, bro.

[arnomertji]

Doesn't look like "P" ^^

[ConnorXV]

Not so much to do with the elemental form but adenosine triphoshate uses phosphorus as it's active component. You probably know

[donnelrj01]

My favorite demonstration of all time is to dissolve some white P in CS2, put this solution over a pressed pill of KClO3 and watch :)

[LeeXai1988]

Yup, putting oxidants together with phosphorus is always fun to watch ;).

[macntechmd]

I love this guys gray afro!

[didia97]

Hello!

Im wondering how phosphorus is used today..

[shortyecu12]

In your body DUHH...lol

[820423]

@didia97 well, one of the uses today is by lighting innocent civilians aflame whenever you need a lightsource in a combatzone so your soldiers can see which ones to shoot and which ones... not to.

At least thats the conclusion one may get after witnessing the pictures of burnt civilians, and listening to the armed forces' response that its used strictly for combat lumination.

Another use would be to include it in various beverages, etc.

[TheVeletlen]

I think Hennig Brand the German alchemist, who discovered phosphorus could be very surprised when got some kind of "life essence" from his urine and in the process produced a white material that glowed in the dark. XD

The disgusting work was worth it! :D:D:D

[MsRejtek]

What a wonderful world! :D

Viruses don't contain psosphorus, they get it from living cells and use it to own activity.

[TruBluFilms]

stfu

[LePeintreOrageux]

70 kg.... that's a LOT :o

[KuferMohamet]

UVF

[KuferMohamet]

UVF SHUT UP

[O3Cl]

The filters from the epitaxy kit I used, did that on contact with air (from the phosphine used decomposing to white P). White phosphorus in aqua regia, now that's a vigorous reaction. Even the tiniest piece lights up like a firework display. :D

[frankensteinmoneymac]

OK all I got to say is that the second scientist to speak.....has the absolute most pimpin' mad scientist hair since einstein!!! I wish he were my teacher!

[frankensteinmoneymac]

Not quite following this.....how did the bottle break, if it was just plugged up and thrown in th ocean....would not the phosphorus just mix with the water then and have no big reaction?

[klodya3]

This is so cool. I am starting to like Chemistry :)

[fuunguus]

What would happen if you eat white phosphorus? I know you wouldn't explode because there isn't enough oxygen inside the body to create enough reactions. I just wonder what would happen :)

[ttucker888]

If you ate white phosphorus you would probably die a painful death. It was once used in "rodine" rat poison (2% by weight) and it is very toxic to humans.

[frankensteinmoneymac]

Oddly enough you can get phosphorus from a certain process involving the evaporation of urine! I think the phosphorus is 'created' by a chemical process rather than being in the urine itself....Also you can phosphorus from bones (cant remember the exact process to make this work) I think it works with both animal and human bones....(not that you'd likely be experimenting with human bones....but

[frankensteinmoneymac]

Uh yeah.....Ive got a bad habit of comenting before I have finished watching the whole video!!LOL As you can see that is what Ive done here....Apparently if I woud have waited a minute or two I would have heard him talk about phosphorus in the body......oh well. I have a right to be an idiot just like everybody else I suppose!:)

[alancj05]

The guy who found it was boiling down a vat of well aged urine, and extracted the phosphorus from the dissolved salts accidentally... IRC.

[frankensteinmoneymac]

Right...I had heard that story...and he did use urine that had been aged....however according to the book I read, he didnt really need to let it age...it would have produced the same amount if fresh....and it would have been quite a bit less stinky!!! LOL!!

[TheFluorineMartyr]

"...some of you may have read Aldous Huxley's novel "Brave New World..."

Me! A good read btw.

[XXL2oo]

Shut up

[Helsingfors]

I won't be posting shit, so I'll come back to life as a banshee and haunt you.

Have you nothing better to do with your life...saddo.

[conman639]

they use this in incendiary grenades

[jasleil]

i nvr know that we make P ourselves

[09876124]

We dont make P elements cant be created or destroyed......

We just have reactions to form ATP

[Raykak]

Fission and fusion.

[09876124]

Not possible in the body.........

I mean you cant imagine nukes exploding in ur body can you

[Raykak]

Of course not, but you claimed elements could not change forms.

[TemplarLucas]

I assume he meant by conventional means.

[ishaanbhola1991]

nice tie........p.s the dense white fumes in the end were of p4o10..

[korrahl]

That just means you are going to die.

[JUNIORROTAX55]

i love they way the guy with the fro uses his hands describe what hes talking about.

[VGMusicRocks]

I must sound like a total noob, but I never knew that phosphorus could just set itself on fire. o_O

also, 39,000th view. :P

[sn1pe352]

what's interesting about phosphorus is when animals die inside of "animal Graveyards" ie, Elephant Graveyards, The phosphorus in your brain and body generate a bluish greenish flame which dances around where your corpse/body was decomposing , perhaps this was metaphorically what the phosphorus plants were poetically representing. I read this from one of Viktor Schaubergers books (A truly unified chemist and physicist). Explain Chemical Reactions in terms of Vibration and Frequency please!

[Mohazesh]

Q: you wanna be like a scientists?

A: ok you can't do that cus you just good in table of food

[BluBreathProductions]

Gibblatron is right. The comment was removed by author.

[BeanangelTreon]

I've read the 70 Kg of ATP phosphorus figure as well I'm thrilled he mentioned it as it is truly amazing most Any reprogramming of the citric acid cycle has vast effects

[jacobssandy]

and good on them for it

[KhmerD0g]

are u saying holocaust is good for the jews? LOL. good one.

[jacobssandy]

no I mean it is good that they use phosphorous since I have always been keen on different elements, especially phosphorous.

[chernobleman]

they obviously care about the nutritional status of the Palestinians. Gotta get your phosphates to be healthy.

[KhmerD0g]

so u have no problem of me feeding you with white phosphorus? hahahhaaaaa. good one.

[chernobleman]

Listen, good nutrition is not easy. But the food pyramid is right.

[KhmerD0g]

ok. i'll take phosphate, u talk white phosphorus.

[chernobleman]

tastes like cheese.

[jamsy00]

Very nice way to present chemistry. OK, today's safety-matches can have red, brown, green heads and maybe some other colours. But it is a strange thing to get upset about it. You won't last long if you get upset about every little mistake in life.

[duskwaith]

Its also illegal if used as anything other than a smoke screen. there where reports of phosphorus burns in the recent Operation Lead attacks.

[bkishar]

The pictures from Gaza show bombs dropping form the sky burning with a very intense white light, very characteristic of white phosphorus. That in addition of course to the hundreds of burn victims reported. Long live the "liberal democracy" of Israel!

[brettrobinson10]

all about astatine

the most useless, rare, impractical and toxic element of them all

lol

[furiousharry]

lol phosphorus is my favourate element too

[pmpknking]

The only thing I knew about phosphorus was that it's one component of glow in the dark paint partly the reason why it glows.

[hereosinerror]

it is not phousflouresent

it just burns brightly like Mg i asked my chem teacher he has a PHD-it might be in paint though

[Serostern]

@howe094 Actually more hazardous to handle it with welder's gloves, Rubber won't do much.

And if he has ben burned before and survived, hey...

[mistahjoey]

Doug Heffernan?

[conoba]

In the old days they used white phosphor for that type of match. But as seen it is far too volatile for that use and got forbidden.

Modern compositions for "strike anywhere" matches use Phosphorus sesquisulfide in mix with a chlorate.

[andrewabbie]

I did...and found nothing to do with white phosphorus being used in matches, just red. Maybe that;s how they do things in your backward ass country, but whatever. I could be wrong...but tbh, what are the odds of both a professor of chemistry and someone studying chemistry at university being outsmarted by a 15 year old kid...

[conoba]

How can you be smarter if you don't know any better and you are even to dumb to find the correct information?

[tomandjj]

he got it wrong white phosphorous in strike anywhere matches and red phosphorous in safety matches.

[andrewabbie]

Yeah, okay, the univeristy professor is wrong and some 15 year old kid is right... How could they possibly use white phorphorus for mathches, they just showed you what happens when its exposed to the oxygen in the air!

[tomandjj]

umm because it was mixed with a compound to make it slightly less reactive ya dumb shit. do your research before accusing please.

[LockeLeCruset]

You got it wrong. It's red for strike-anywhere matches and safety matches use an entirely different mechanism.

"Dumb Shit". So eloquent and intelligent for the 15-year-old who thinks he has outsmarted an experienced Chemist.

Go do your homework and your research.

[tomandjj]

wow it took youlike a month to reply. No look it up My uncle helped make the modern match formulas red phosphorous is safety matches e.g. redheads made today in Sweden. White phosphorous is for strike anywhere matches also made in Sweden but only legally sold in a few countries/states. Don't be a retard next time.

[TimmyTheGreatOo]

white phosphorus ist highly toxic, they don't use it in matches anymore (but they did)

[tomandjj]

still legal in some countries so it's still manufactured for those countries.

[RandomDota]

they use it in grenades ,,,

[Jammin67]

what i wanna know is it responsible for farts????

[awol09]

hydrogen sulfide gas= the rotten egg smell of farts

[19thAndy]

haha look its einstein !

[darkenmyeyes]

wtf that guys hair

[farishino]

oh my goodness. his tie.

[JakeEricson]

Wow, these are the best videos evar. Subbed.

[chocolatepieeater]

haha the guy with the cool hair is the best. look at his tie. freaking awesome. haha.

[PcJaiden828]

do you think taht phospherous has something to do with SHC? i always thought it had somethin to do with the chemicals in your body.

[Gruntol5]

The chemical properties of elements are quite different from their compounds. Phosphorous compounds in your body are no more "explosive" than is the sodium in sodium chloride. When you sprinkle salt on your food, do you think it might burst into flames? Once an element has reacted to form a compound, it is in a far more stable state - that's why most elements do react with other elements - so that they can attain a "lower energy state" giving off heat and light in the process.

[PcJaiden828]

well thats something we can al think about.

[nitrex]

Read murder,sorrow and phosphorus, a book made by john emsley, He explains SHC with Diphosphanes forming in your body, which he says can be the case of Diphosphine fires.

[666Luftballons]

"Phenomena" is plural, fool. Stop trying to be smart (and maybe some time, on a clear spring day, when bees are humming and lovers kissing, I'll stop being rude).

[blitzfalcon]

Wow, this is so much better than textbooks... will recommend this to friends..

[metaspherz]

I never knew that the average human body had so much phosphorus in it. Might the production and retention of large amounts of phosphorus in some persons account for the phenomenon called spontaneous human combustion (SHC)? Crime scene photos have suggested that the phenomenae isn't just in the realm of folklore but that it occasionally does happen. Maybe the combination of alcohol and phosphorus in some persons has something to do with SHC. Such a death would be horrendous.

[ProphetTenebrae]

Pretty much every single credible piece of research into SHC suggests that it involves incapacitated individuals and a source of ignition, with the clothing acting as an inverted wick and the body's fatty deposits burning with great intensity in a very localised area.

Horrendous, certainly but there's nothing spontaneous about it. Wiki has a rather lengthy article about the "wick effect".

[metaspherz]

That may be so, however, many crime scene photos often include mobile victims. Much of their clothing and furniture did not combust suggesting an internal heat source. High alcohol levels were evident in every instance. Our bodies produce alcohol as well, some bodies more so than others. Mightn't an abundance of alcohol in the cellular structure plus reactive phosphorus contribute to the SHC phenomenae, even when fat wasn't a factor? Dehydration surely plays a significant role as well.

[ProphetTenebrae]

Where's the reactive phosphorous? And even without looking it up, I'm extremely dubious that alcohol could exist in quantities sufficient to aid combustion.

And as far as I'm aware, all instances that have been documented in any detail have supported the inverse wick theory... so I've no idea where your "internal heat source" notion is coming from.

[AlmightScoop]

Yeah - theres loads. Not just in ATP and ADP, which Prof. Poliakoff mentioned, but it also holds our DNA together and theres a lot of it in our bones, which are made largely of hydroxyapatite ( (Ca)10 (PO4)6 (OH)2 ). However, is all these biolofical forms, it is vastly more stable than in the elemental forms shown (black, white and red) and would not be reactive enough able to account for spontaneous human combustion.

[johnclavis]

These videos are such a delight. Thanks to *everybody* involved in making them!

[CrackBadger52]

The lad with the gray hair looks like a mad scientist

[sepultura1982]

The first guy looks like Trigger Happy TV's Dom Jolly

[omfgwtfroflol]

so it can generate a nice P!!....for phosphorus lol

[0Linerider0forever0]

PHOSPHORUS FTW!
