Lithium - Periodic Table of Videos

[kiddolols]

lol i threw enough in such that it caught fire and had a little explosion!

[jayejayeee]

you have some great stuff here

[xtremetom180]

i enjoyed this vid

[smuggecko]

love the work here

[TheSpikeystuff]

very interesting thanks

[PorroFirst]

I would never have thought I'd hear this guy talk about Nirvana.

[TommyNegeal]

[RuneFinity44]

We watch this video in school today.

I got suspended because I said "Lithium is such a whore, she'll react with anybody, sucking on their electrons... tsk tsk"

[Izzegulle]

@RuneFinity44 That's probably only because what you said is wrong. Lithium gives away it's electron, and therefore does not "suck" on others electrons! Nice try though ;)

[RuneFinity44]

@Izzegulle

Lmfao, you're a nerd bro.

[F34Ri]

@Izzegulle

Wow, your a fag. Ruining everyones fun, you kill joy. Nice try, your mexican bitch.

[6sinclair]

thanx for making this vid. I have to write a 500-700 page report solely on lithium once again thanx.

[DevilMaster]

"If you have a fire with lithium you can never put it out". Not even with halomethanes (halon)?

[Tridecalogism]

Periodic Video's! Y U NO ON DVD??

[ujwalreddy11]

gud 1

[renatamanidifata1]

thanks for the videso , they help me understand a lot!!!

[Feskon]

can somebody say me whats nitrogen in german? ;) "it reacts with the nitrogen in the air immidiently"

[renatamanidifata1]

@Feskon

Stickstoff

[AraGuitar]

I'm so happy, 'cause today I found my friends - they're in my head.

[6sinclair]

@AraGuitar  im so lonely,thats ok cause so are you

[hupper12345]

I want that periodic table cup!!!!

[OOZ662]

Lithium Flower, sung by Scott Matthew and composed by Yoko Kanno.

[TheCaptainLulz]

I get my lithium from button cells I buy at the dollar store (3/$1). Its really quite fun to do chemistry with it. Im also on Lithium Carbonate for my brain (900mg/day). This stuff is in my life every day, so its always fun to learn more about it.

[ilvmusiclol]

if in doubt, use a torch...

[chocolatechocochoco]

il a vraiment une tête de scientifique fou lol

[slLLyhumans]

Oya Nirvana .

[snipesnrifles]

lithium by nirvana ;)

[puncheex]

BTW, it is useful to note that the Prof mentions burning lithium as being difficult to halt. The burning seen in the experiment is not the same thing; that is simply hydrogen generated in the reaction burning with oxygen. Lithium burning is very much the same as magnesium burning (the brilliant white in fireworks and military parachute flares) or aluminum (the shuttle SRB fuel, essentially).

[progunist]

Nirvana- Lithium

[DracoMhuuh]

@progunist Don't forget Evenescence's lithium

[gaussman08]

oh dammit , all this time I thought Nirvana was a grunge band and just now you tell me it was a pop band!? SHIT I'ma fucking idiot!

[ausalyb]

I've been using your videos in my 8th grade physical science class. The kids really love them - and especially love The Professor. I admit - I love him too. He makes me want to go out and get some prescription safety goggle glasses to wear all the time. It's like The Professor is ready to do chemistry at any moment! I love your enthusiasm for what you do. It is contagious!

[brianbert907]

lol is that professor from half-baked

[sternau101]

EINSTINES BACK!

[axnasia1]

Amazing. More reactive than I thought.

[Desmaad]

You forgot to mention it's use in batteries.

[skaterboy5884]

THE PROFESSOR LIKES NIRVANA!!!!!

[calv1nchang]

@skaterboy5884 !!!!!!

[TheCaptainLulz]

I take lithium, it makes you quite drowsy. Apparently it can protect the brain from alzheimers aswell.

[snipesnrifles]

ur periodic table mug is awesome

[retc90]

I am a junior chemistry student. your videos help me alot. I take in lots of info besides of what i learn in college. Thank u.

[ArmoredWerewolf]

i want a mug like that

[DjinnJuggler]

I love all of your videos, they are very informative and I've learned so much from them. You've inspired me to start my own blog of collecting elements, there's a slideshow about it on my channel.

[TheKenya42]

nice hair

[masacatior]

it isn't spanish, it's portuguese, and probably there's a lot of brazilians on youtube and im one

[calvinator9111111111]

Possibly the coolest hair i have ever seen.

[HardyBoyTyler74]

Lithium by Nirvana, though it isn't a "pop" song. xD

[MelvinSF]

@HardyBoyTyler74 Maybe he was referring to Lithium by...Evanescence if I recall correctly. No clue if that classifies as pop as I never listen to that kind of music.

[HardyBoyTyler74]

@MelvinSF Lithium by Nirvana is about when Kurt Cobain (the lead singer and guitarist) took lithium for his bipolar.

"I'm so happy, cuz today I found my friends, they're in my head. I'm so ugly, that's okay cuz so are you."

[missyloulawless]

And in Crystal Healing we can use minerals with a high lithium content in an energetic way to soothe excessive emotions by keeping stones like ambigonite or lepidolite close to our own energetic fields: we can wear them as pendants, keep it in our pockets..

[behbf]

That song Lithium Is not pop music its A Rock Song By Nirvana.

[Shmilli]

That's funny, my teacher in my first chemistry course also mentioned Nirvanas song "Lithium" when he was talking about the compound ^^

I find this channel both entertaining and very interesting. I have an exam in chemistry in a couple of weeks, and additionally to studying with my books, I watch these videos that you guys make, just so that I can get that little extra ;) I'm hoping to see some more videos about organic molecules from you (I especially enjoyed the benzene-video). Thank you!

[murderousrage]

did the professor just make a nirvana reference?

[Eyedunno]

@murderousrage

I think so! Looking at the sidebar, it looks like there's also an Evanescence song. He did say "at least one" though.

[XFactor35]

Thank you for these videos - I absolutely love them. I have a request for a video topic: can you ask Martyn to explain different kinds of elemental allotropes? I know he described some allotropes of phosphorous (red and white specifically), but I would be interested to learn about other exotic allotropes and their uses.

[bibabuwhatever]

Nirvana - Lithium

[OGdank13]

#LOL his hair is awesome

[T3rM1n8TOr]

0:30 #OMG i thought that guy was wearing a wig! :S

[lizedine]

@T3rM1n8TOr I think it's real..Lol...

:D

[okmasko]

2:15 nice cup :D

[rainor94]

That guy has some sick hair.

[jess2you]

these videos should be seen in the highschools... very educational... love the crazy mad scientest hair LOL

[nayrnayr93]

that haircut...wow

[b1u3too]

Nirvana also had a song called Lithium. Unfortunately, other extrenuating medical conditions can prevent a manic depressive from being able to use lithium as a mood balancing chemical. Enter the pseudoscience that is psychiatry and the fine art of figuring out while medivines have just the right side effects to treat a manic depressive.

[mozzarell]

I love science

[firstdarkdrama]

Any plans to release any of your series' outside of Youtube (i.e. downloads or DVD)? Really love your work!

[blicblak]

why do the subs automatically go straight to Portuguese? You'd think it'd be English, but with ou instead of just o in things like colour.

[01reyaz]

Evanescence - Lithium lol :P professor is so kewl...

[Sparkleslovestosmile]

I have that periodic table mug!! Im a science nerd :))

[exibitions]

Professor...that pop song has nothing to do with depression, I assure you...it has more to do with lithium as a illegal drug.

[risbolla]

Nice cup

[jacowaco10]

Lithium is one of my favourite elements, by the way, pimpin' afro man.

[culwin]

LOL I love those Nirvana boys with their pop songs.

[adeeply]

i wana more about the lithium function in the battery cell =)

[AJFreeway]

Dirty nappies, lol

[ScottRoseVideo]

I just have to say at school I had no interest in chemistry (I only liked space and physics, ha!) Since I subscribed to this channel I've found chemistry to become a real guilty pleasure. This said it may just be more mature thinking but I seriously think lecturers could learn a lot from these videos. Not the content but the format, all the school videos I watched where out-dated and treat you like a child, I would love to see these implemented in school!

Regardless thank you, love your videos.

[periodicvideos]

@ScottRoseVideo Thanks for the kind words. We also think school students like videos which are not "made for students" but simply talk to everyone as equals.

[KsAnNa]

@periodicvideos I've shown my IB Chemistry teacher this channel. She plans on using it for her classes.

[p6a9u1l42]

if my high school had this when i went through high school i would have loved science a lot more than i already did

[Xeidasx]

why is the captions in portuguese?

[periodicvideos]

@Xeidasx We have a professor in Brazil who does translations for us.... Anyone can turn off captions by using the button at the bottom right of the player.

[temporaldisplacement]

@periodicvideos Big intellectual movement in Brazil in recent years if I'm not mistaken. ...all good. ^.^

[rjhrjh3]

The professor said "Cannot put out a Lithium fire." Would love to see them do experiments where they demonstrate this. Say put CO2 and other common fire fighting chemicals onto such a fire.

[whitehiliter]

Oh, also it isn't a pop song, its grunge, completely different. Lithium by Nirvana... Grunge is sort of a dark style of rock.

[whitehiliter]

Please take the spanish subs off plz... super annoying.

[periodicvideos]

@whitehiliter You can turn off captions yourself. Use the button at bottom right of player.

[whitehiliter]

@periodicvideos Oh, I thought the captions button was a red "cc" button next to the video quality. My mistake lol.

[vizcacha5]

@whitehiliter its portuguese tard

[Bodybuildingryan2]

@whitehiliter The spanish sub's arent annoying for people that speak spanish.

[whitehiliter]

@Bodybuildingryan2 How many people that are subbed to this channel and watch these channels ONLY speak spanish? Prob none.

[IceStorm5555]

Great video except for the translation near the end of the video , the text is in the middle of the screen and not at the bottom a bit annoying.

Best Regards,

IceStorm

[StaupEimer]

The song is actually Grunge. It's by Nirvana if you want to look it up.

[Kobayashi113]

i really love these videos. i hope periodicvideos read this comment!

[500lbkoolaidman]

Hip hop song? Referring to Evanescence?

[clarkcolt45]

@500lbkoolaidman lithium by nirvana of course, a classic, but not hip hop

[ShortGuy1792]

It was mentioned that a fire with lithium cannot be extinguished. I'm curious. What temperature does lithium ignite at?

[BanannieMoo]

rofl !!!

love the prof's afro <3

[TheEchoesofMetroid]

what causes it to react with water? Just it's properties? Or does it have to do with breaking hydrogen bonds and all that? (sleeping through high school chemistry was a mistake considering i enjoy the subject <_<)

[carlsoto1747]

@TheEchoesofMetroid It reacts with the oxygen in the water. He mention it will produce H2 as a bi-product. Its a simple single replacement reaction.

Li + H2O ----> Li2O and H2. (Lithium Oxide). It also reacts with Nitrogen gas in the air. It also with the water vapor or oxygen in the air, whichever has a high enough quantity to make the reaction go 100%.

Li + N2 -----> Li3N

[TheEchoesofMetroid]

@carlsoto1747 thanks!

[puncheex]

@carlsoto1747: Ummmm, I'm kind of doubtful about Lithium oxide. I think, rather, that the Lithium is joining with a hydroxyl ion:

2Li + 2H2O → 2LiOH + H2

The other equation should be

6Li + N2 → 2Li3N

which then reacts with water (violently) to yield ammonia, as the Prof mentions:

Li3N + 3 H2O → 3 LiOH + NH3

[puncheex]

@TheEchoesofMetroid: Lithium, like all alkalai metals, has one loose electron by itself in an outer shell. It wants badly to ionically bond to an acidic, like chlorine, fluorine, or in this case a hydroxyl ion. Badly enough to rip stable water apart to get to one. See the reactions below.

[puretroubleman]

why no mention of lithium ion batteries?

[trunkszetto]

@puretroubleman that would probably entail some sort of explanation of galvanic cells which is kinda out of the scope of this video. but yeah, they should have at least mentioned it.

[StarcrossedPacific]

I would appreciate it, if in the future you could include chemical formulas along your explanations.

[chris7toronto]

Poor lithium reaction..

[ukanid]

well chinese subtittle was going to help me more

[DG121480]

So, it smells a bit like dirty... What?

[Brudof]

@DG121480

nappies = diaper

[DG121480]

@Brudof

Right. Got it! Thanks!

[puretroubleman]

@DG121480 Nappys are the term brits us for what you'd call diapers

[TeacherPhilEnglish]

Evanescence has a song called lithium too

[magicicle]

Neil is so hot <3

What I wouldn't do to spend a night with him ;)

[JFooBo]

lol i wouldn't quite call lithium by nirvana a pop song

[samn100]

I would be happy for a year if periodicvideos says hi

[periodicvideos]

@samn100 Gosh if that's all it takes, then "hi"... hope you're subscribed to this and to sixtysymbols for our physics videos!

[samn100]

@periodicvideos YAY

[skylitebanditt]

" so it smells a bit like dirty nappys " rofl 2:25

[RJLeffmann]

Great video, but how long before the HD kicks in? At the moment it's just low resolution video material that has been scaled up to HD size.

[LacedShit]

wish you guys would add cc option so we could turn off if we wanted!

[periodicvideos]

@LacedShit You can turn it off..... The little arrow menu at bottom right of the player.

[flamingarse1]

it it really impossible to put out a magnesium fire

[CptDoodles]

yay the prof knows nirvana XD

[myrmecophilous]

hahaha I love that the professor cites a nirvana song.

I can't believe lithium is reactive enough to react with nitrogen. That's just crazy. Nitrogen is so stable usually.

[myrmecophilous]

@myrmecophilous oh wait apparently it could also have been a song by evanescence. Well I'm just going to assume he meant nirvana because evanescence is such utter shit.

[thewiseowl]

@myrmecophilous Well given Lithiums uses in treating manic depression and Kurt Cobains demise I think we can safely say he's on about Nirvana.

[myrmecophilous]

@thewiseowl Good point.

[redone632]

You mention that you keep a lot of metals under oil. Does anyone know what kind of oil?

[ssnp]

@redone632 i think it is mineral oil but i'm not sure

[Paxmax]

Hmm.. can it be used as a super light and strong alloy if stabilized?

[puncheex]

@Paxmax: Light, yes, but not very strong. For light strength use an aluminum alloy or for extreme hardness titanium (very hard to machine, but used as armor in airplanes, such as the A-10 warthog).

[Paxmax]

@puncheex Titanium is not any particularly hard, when it comes to armor the name of the game is shock resistance and being ductile. Many steel alloys totally rule this. The tradeoff for aircrafts is weight and that's one key element in favor for titanium.

Titanium nitride is a really hard substance but too brittle to be useful except for coating.

Yes, machining is a nightmare with small margins for error.

Was thinking of getting a Ti frame bike, but I went with carbon fiber, looks awesome.

[Paxmax]

@puncheex Oh... and who doesn't love the warthog!!! =o)

Spray some boxes of 50cal at it, shoot off half a wing and kill one engine and you'll still fly home! Not many aircrafts can take the punishment A-10 can withstand.

...and maul anything above surface you throw infront of it. Love at first sight!

[cowcake333]

NAPPIES!

[DeathlyCrunch]

>Nirvana

>Pop songs

Oh you.

[shadowgamer31]

That afro HAS to be a wig, in order for the world to make sense.

[sodium95]

@TeoTheAwesome yess i would like too see a video about tritium...

[dlacc187]

sidebar - how does the professor maintain his afro? can we get a video on that?

[Danluna58]

@dlacc187 His brain is filled with so much knowledge that it uses his hair as extra storage space.

[ObtrusiveDave]

@Danluna58 heh

[ObtrusiveDave]

@dlacc187 lol

[TeoTheAwesome]

I would love to see a video on tritium since tritium can be made from lithium. And after that maybe a video on deuterium and nuclear fusion :)

[Blinkwing]

@TeoTheAwesome i have a little portion of tritium in my room :D you too?

[TeoTheAwesome]

@Blinkwing Sadly, no. But I would love to get one of those cool tritium watches :D

[puncheex]

@Blinkwing: An exit sign?

[Connelly90]

"I'm so happy 'cause today I've found my friends, they're in my head" :D Lithium

[MusicMan20061210]

It would be interesting if you did a follow-up video on the enormous salt flats of Bolivia,that contain the greatest supply of lithium in the world.

Which is of interest to battery manufacturing, e.g. for the possible future of electric cars.

Thanks

[xKxDR3WxKx]

i have that mug :)

[iionious]

fifth

[Maxstate]

DIRTY NAPPIES

[drokles]

Is the Professor talking about Nirvana, do you think?

[Smalas]

@drokles No, I believe he is talking about Evanescence's song Lithium.

[TeoTheAwesome]

@Smalas Isn't there also a Nirvana song called Lithium? Although it's more likely to be Evanescence's song because the professor said it was a pop song...

[dlacc187]

@TeoTheAwesome uhh...that was one of nirvana's biggest songs. its an insult to even mention evanescence in the same sentence.

[Zed1967]

@dlacc187

Oh no! Let's all go emo because someone mentioned another band in the same sentence as Nirvana in the comments on a video about chemistry. *rolls eyes*

[dlacc187]

@Zed1967 jump off a cliff while you strum your lame acoustic guitar, you middle aged hippie douchebag. thanks :)

[DeathlyCrunch]

Yeah, acoustic guitar is totally lame and not metal eh? I'm sure such a brutal and cool guy such as your self can play any sort of guitar can't you?

[dlacc187]

@DeathlyCrunch i don't even like metal. now get off my dick you lil hentai loving freak.

[carpeinfinitum]

@drokles  sure seems like it!! =D

[portugal0are0da0best]

@drokles quite possibly

[ProtoisRob]

Always liked group 1 metals.

[dlacc187]

@ProtoisRob lmao. why?

[Stifflerino]

Im irish.
