Reactions of group 1 metals

[@mancheeeee]

I feel like eating the metal piece cus its so soft but it will explode in my stomach Residue: death Oxide

[@JayMark2049]

''And as you can see here I have three full bricks of Li, Na and K now let's dump them all into water like so...'' *Room bursts into flames*

[@grass9047]

AHAHAHAHAHAHAHAHAH!!!!

[@tallchief22]

240p... we meet again

[@wilsonblauheuer6544]

chris cautillo why are the metals easy to cut because they are soft.

[@f.jideament]

Hello darkness my old friend

[@coololly]

14:33 the best part

[@eebeeby]

7:58 "We need to cut a piece off..." K

[@Yash_SG8]

I loved the pop sound of H2

[@hueyfreeman1603]

I felt a strange craving for steak when she cut the lithium.

[@chemical_x5350]

this video has increased my love for chemistry...😘😘😍😍💜💜

[@chittisatish8592]

Yeah its right

[@pir8gurl1021]

Found this while studying alkali metals in science class.Epic. Nuff said.

[@DavidRussell323]

It's super rare. As little as 20-30 g (one ounce) exists at any given time throughout the Earth's crust

[@Yash_SG8]

Made my day for the exam. I mean who'll read the theory? I have stuff in front of me!

[@TheGrimReapress]

now that's the BEST scientific observation eva (thumbs up)

[@mancheeeee]

i just watched this vid again and again to see the satisfying cutting of the metals

[@arsenmuja]

how can these scientist be so sensible, if that was me i would burn a whole chunk of pottasium and dont get me started about cesium... that would be my next best friend.

[@pankajprasar]

please re-upload video in HD Quality.

[@royalsocietyofchemistry4447]

Hi pankaj prasar, I'm glad you like this video. Unfortunately we don't have a higher res version to upload, but I hope it's useful nontheless

[@seshachary5580]

great teaching. thank you.

[@idijoost]

Unlike school, here you can skip to the interesting parts!!

[@zbret]

A suggestion - when passing around the petri dish(s) to show how light they are, also send around a "control" (empty dish) so one can see they almost weigh the same in one's hand. (add equal tape amount to the control as well if you tape the others).

[@aseemmann]

These videos are sooo helpful :D

[@EbenezerGeorge]

thanks for taking me back to my chemistry classes. i love chemistry

[@PHATTSTER]

Just had a phone call from ELTON JOHN.......says he wants his glasses back!!!!

[@AdrianTheImmortal]

Francium is an extremely rare meterial, also its only held in controlled environments, due to its volatile nature.

[@topherc100]

why are the metals easy to cut

[@bilalzafar2871]

Since they have larger atomic size that decreases down the period that why their chemical property makes them soft

[@ReubenLL28]

Drying with paper towel doesn't seem any safer than using Hexane. If you were to wipe the potassium with the paper too hard, for example, you could cause the paper to oxidize the metal (causing a fire). This wiping could also induce a reaction between surface potassium superoxide and potassium metal, depending on how corroded the potassium is (again, causing a fire).

[@johnromanas]

Is it sodium oxide or peroxide ?

[@Cheeseboat20]

Francium is extremely rare, with trace amounts found in uranium and thorium ores, where the isotope francium-223 continually forms and decays. As little as 20-30 g (one ounce) exists at any given time throughout the Earth's crust; the other isotopes are entirely synthetic. The largest amount produced in the laboratory was a cluster of more than 300,000 atoms. That's why no francium.

[@THENIGHTELFKALDOREI]

Fist off Francium is Highly Radioactive-the longest isotope of Francium is Fr-223 with a half life of 22 minutes. Second, because of its high radioactivity, Francium doesn't last that long (obviously...) and can only be worked with if the chemist, physicist, etc. has a Level A Hazmat suit or a CBRN suit on to protect from the radiation

[@fcinternetmarketing]

Very helpful for science students.

[@TheMrCraniumZ]

Exact same thought. I was about to write that as well lol

[@E90PAT]

My school is too poor, theyll just show this video instead

[@CatboyChemicalSociety]

u know i have a wierd urge to bite into the sodium ingot but obviously it will blow up my head

[@bilalzafar2871]

Will the digested sodium go into your stomach or your head lol it's funny

[@itszayonide3602]

helped a lot thanks👍👍☺☺☺

[@Aslyuriel]

cesium isn't radioactive >.< . is it?

[@drexlerf]

group 1 metals have 1 valence electron, which makes them extremely reactive. it could react with almost anything, but oil isn't reactive with group 1 elements.

[@UkehuntSir]

oh wow shes interesting to listen to, such a captivating voice ¬____________¬

[@APOCELITEDEATH]

@THENIGHTELFKALDOREI yeah, but no one can even work with francium because it is one of the most rarest elements, and no one has ever made a synthetic version if it.

[@RealQuin]

why can't you touch the sodium? its not poisonous right?

[@denvera1g1]

no, only cesium created after a uranium fission reaction is radio active

[@fofighting]

Also, francium is almost never with it's outer electron. It loses it so easily, it never actually has it, except for the instant of a nuclear explosion or something that produces francium

[@adeliaerlina8533]

what indicators are used?

[@heyheyzx]

so the water in the atmosphere don't chemically react with the metals

[@TheLocalDJ]

1. This is for school purposes, they are not allowed to test for anything more reactive than potassium due to the violence of the reaction. 2. Francium is radioactive and next to impossible to obtain. 3. Yep haha

[@MusisProductions]

WILL SOMEONE JUST PUT FRANCIUM IN WATER ALREADY!? IM NOT DYING UNTIL I SEE FRANCIUM ENTER WATER EVEN IF I DIE PUTTING IT IN!!!

[@101warda]

good video it teaches me well

[@GameFreakBot]

I thought that the brick was all lithium. I was like "must put whole thing into water!"

[@faysalfaarax3478]

thank you lesson I'm somaliland

[@matthewprice526]

stops it oxidizing or reacting with air, like she says in the video, when the shiny part becomes dull, that's the metal oxidizing, NOW LISTEN IN CHEMISTRY CLASS

[@Dajziopolis]

AWSOME!!!!

[@lukaseriksson4975]

where do you get your metals?

[@APOCELITEDEATH]

@apard7 no but francium is.

[@vitthalramtakke4447]

why r u using that circuit tester

[@Jex134]

Most people don't like handling radioactive elements that you can't stop from exploding.

[@marcOantoni0]

so they wont react with the moisture in the air

[@deaftodd]

Where's the fume hood?

[@x1xpeacemakerx1x]

im curious, what would happen if your skin has contact with lithium?

[@wtrmln]

No, cesium isn't radioactive. Francium is radioactive ^^

[@jaysn1683]

Why do you use chlorine and not fluorine?

[@jaysn1683]

Well, thanks alot! :)

[@rajeshshahi1000]

+Royal Society Of Chemistry fluorine is the most reactive element known to man.

[@haotinghuang3736]

She said: Fluoride is the most reactive NON-metal.

[@saeedakhan8877]

because the reactions with fluorine are explosive releasing too much energy

[@EMac06]

umm not all metals react to electricity

[@MrNoBody114]

do u have some?

[@thertsman8233]

group 1 is my favourite group

[@APOCELITEDEATH]

@gregod10 it IS more reactive than cesium. It has only been tested once and it exploded in Area 51. There was a little test room and one man was killed.

[@AlMayer1100]

Why is Kalium (K) called Potassium (lol) in english?

[@nindocomic]

-As you can see... the shiny SILVER SURFER!!! ...

[@300zxgreg]

can you cut an atom with that scalpel?

[@vitthalramtakke4447]

why u r using that wire like machine

[@nickbhalo]

Francium is so radioactive it is impossible to get a usable amount of it... sadly

[@MrGunnaras]

cuting metal with a knife.... why the hell did i study as a blacksmith 4 years?

[@doormagic]

13:45,nice.

[@Bashamo257]

what? No francium?

[@Sneakydud2]

and it also blocks off oxgyen

[@RandomGuy9894]

I don't think there is enough francium to give out. Also is highly radioactive.

[@bomber4441]

But that K could get a exploseve cowt if left in oil for to long

[@JuanGomez-mv1qx]

Awesome

[@coleslaw1107]

Its difficult to cut because the knife is blunt

[@kennethandrew4356]

The most stable isotope of Francium has a half-life of 22 minutes.

[@louistournas120]

She did throw it in the water.

[@Wallhackingplusesp]

Francium?

[@macdaddydipper]

Too dangerous

[@Wallhackingplusesp]

Yes

[@trantuandungvu7961]

It's radioactive

[@trantuandungvu7961]

Cesium and rubidium are dangerous

[@dragonslayer050819]

why is the metal soft?

[@IAmThatTeenager]

francium is extremely radioactive, it has a half-life of 8hours, and because of this cannot be produced stabily for any period of time as it almost completely disappears after a few days no matter how you store it. so in total, Francium is ludicrously radioactive, ridiculously radioactive and has a shorter shelf-life than dodgy vegetables, so not probably the best example to use

[@DubstructorMusic]

name one non-conductive metal

[@dgamezonu2693]

Lead

[@JerryGiesler09]

Notice you forgot to tie your hair back when working with expriments like that. :/

[@Nikolaii2571]

No Francium or Cesium-137.

[@StoreAway]

Nice.

[@slein3]

Becuase Francium is highly radioactive

[@iElite6809]

Well, I have a Cargon.

[@Nikolaii2571]

No Francium or Cesium-137. ;-)

[@PartisanGamer]

its caustic

[@isaacoscar1]

obviously if he is watching this video he understands that.

[@13Psycho13]

now try to throw Plutonium in the water

[@Jellycrusher]

In fact they are reactive because of their low electronegativities AND low ionization energies. Number of electron is not critical here. Fluorine or chlorine has seven electrons and it's also extremely reactive - and in this case is is caused by their high electronegativities AND high electron affinities. These two factors must occur both. There are some element which are characterized by only one of them, and they are not so reactive.

[@MaximeGrenier11]

It would have been cool But dont think anybody on earth can get enough Fr to react out of the 40 gramms that are constantly reacting and re-creating ( if I can say so ) simulteanously on all the earth's surface xD.

[@HamoodyDarbaDoody]

they chose to live.

[@russellh784]

I have an urge to bite a Francium ingot

[@MrAlexandremarus]

Googling it

[@ZehLukinhas-GamesCompilation]

hahaha amazing

[@VannyProduction]

12:35 Na goes weeeeeee :3

[@Sneakydud2]

my car is made out of pure sodium

[@MusisProductions]

Maybe she did use francium, it just blew up the camera and the whole lab which is why they couldn't send the video on youtube XD

[@TheGrimReapress]

eeer, nice doing all that, very scientifically ok, but what's up with the hair? First thing they tell you before you walk into a lab is - no chewing, no drinking, no eating, PPE worn (gloves, specs, labcoat) and HAIR TIED BACK! I know, I know, she's not doing dangerous stuff with fire .... oh wait, she is! I've personally watched a classmate of mine burn half of her hair on a bunsen, so please tie it back. Otherwise, content wise - brilliant video.

[@DnDFizban1]

dont know about you, but im pretty sure there is no such thing as a black snmith metal...

[@Jex134]

That was a poor explanation. . All elements do seek to have 8 valence electrons, some try to steal electrons to get up to 8, like those with 6 & 7 valence electrons, while for others its easier to eject electrons to get down 1 orbit layer, ejecting their 1 valence electron (via a reaction) exposing the 8 on the next row down, making them become the valence orbit. . The difference between stealing and ejecting is like rounding up or down in math. Sometimes its easier to go up, sometimes down.
