The energy released increases per atom, not necessarily per mass, and since rubidium atoms (and caesium) are much larger and heavier than sodium or potassium you might not get the huge explosion you are looking for.
I think it failed because when te hamer struck the vial it may have somehow split the block or weakened it so that way it could come apart after the initial explosion...better luck with francium :P
@mikidof wow, that was a long time ago, yes now I know it was a bit of a fake (very exciting to watch at the time though), the number of people brainiac might have brought to enjoy science though might be quite a large one so as long as it isn't an outright lie to real science (ok it was a little over the top) it is quite a good thing :)
What i think happend was the glass ampule didnt shatter and the rubidium fell into the water with the glass ampule. and with the little opening which was broken in the ampule only a small surface area of the rubidium was shown, and the Rb is iside the glass ampule it must have acted as a shock absorber too.
@analyzingfunny They are not physicists. What ever their profession is, I am highly certain that they are a lot more knowledgeable than you. Don't say you are a "professional" or have a PhD. Your level knowledge has already been shown in your comment.
Hey, The YouTuber Thunderf00t said that Lithium is more reactive than Cesium.... and the rest of the Internet tells me the opposite. Which one is correct?
The alkali metals become more reactive as you go down the group, so the least reactive is lithium, then sodium, then potassium, then rubidium, then caesium, then francium . . . so yes, caesium is a *LOT* more reactive than lithium.
@LuxuryBarrage He probally meant Lithium is more reactive than Cesium under certain conditions. Like for example some elements react to magnetic fields while others react very little if not at all.
@LuxuryBarrage Cesium is more reactive than lithium under all conditions. The reason why Tf00t said lithium is due to the molecular mass of the atoms. 1g of lithium contains more atoms than cesium. About 20 times more. The reaction occurs about 20 times more than the cesium-water reaction. This cancels out the fact that cesium releases more energy per atom. However, if the volume of the two metals are the same, cesium will release more energy. NANOFORGE was wrong in his reply to your comment.
Take it all out of the container, chop it into tiny pieces, and seal it in waxpaper, then drop it in hot water. The wax will delay the reaction so it sinks to the bottom and it'll be like a little under water clusterbomb, it's also a safe means of delivery.
DO NOT drop Rubidium metal into Nitric acid. As a pyrotechnitian I have burned other salts of alkali metals. Potassium may produce a magenta and/or a lilac color when burned. Sodium produces a bright YELLOW, not orange color. It is Calcium that imparts an orange hue into the flame. Strontium for red, Copper for either green or blue, and Barium for green (and sometimes white). Boron can also produce a greenish flame. I would like to experiment with Rubidium nitrate for starters. Thank you.
Part of the disappointment/fizzle here is related to the fact that rubidium has a heavier molar mass than sodium or potassium. So a 1 gram sample of rubidium has approximately 1/85th of a mole, whereas 1 gram of potassium has 1/39th, 1 gram of sodium has 1/23rd, and 1 gram of lithium has 1/7th of a mole of atoms.
To do a true comparison equimolar samples should be tested rather than equal masses- it could get expensive and dangerous though.
unlike this where the glass may have inhibited the reaction and the reaction started ontop of the water where I think it stayed, poorly transmitting the shockwaves giving a bubble bath instead. Not saying the braniac is definately real but it's all in the entertainment.
About this brainiac stuff. In brainiac they used dissolving glass which allowed the Rb to sink to the bottom of the bath and then uniformly react with the water, creating a shockwave which was transmitted fully to the bathtub making it break,
@periodicvideos It seems that they forgot the molecular weight in order to calculate how reactive it was...
lithium has a weight of 7 grams per mol, sodium 23 g/mol, potassium 39 g/mol and rubidium about 85g/mol.
if the reactivitity energy were the same (that is not the case) then 2 grams of rubidium would be the same as half gram of sodium, and 165 miligrams of potassium!
The reactivitiy cannot be predicted using the periodic table...
@periodicvideos They were indeed assisted with explosives, there is actually a video explaining how these reactions must be fake proving it with your video in particular! /watch?v=jhg0WsINmPc Just watching the brainiac video, you can see a wire going into the bathtub, which I presume is linked to some type of explosive, which they detonated at the time the Rb started to react.
@ConnorXV I just watched it I think it's cuz by the capsule that contains it they had it with something like a polyester capsule that wud dissolve in water so when the capsule dissolves most likely uniformly wud create a a large surface area instantaneously, causing a high explosion whereas in this videos case hammer falls pieces of Rb fell.
@ConnorXV the reaction is very violent, but not that violent, the explosion is powered by hydrogen gas, so the heavier the alkaline metal the faster the hydrogen is released and ignited. in other words, you just get a nice cloud of hydrogen and tiny flakes of rubidium, even francium would just be like filling a balloon with hydrogen and oxygen and igniting it. however if you put sodium on a stick of dynamite and sprayed the sodium with flourine it may cause the dynamite to detonate.
Firstly, top job on all these videos, I really enjoy them, I wish Martyn was my grandad. Secondly, people probably always ask this but, when are you guys going to dunk one of these metals into some conc acid?
Whoever thinks this is fake your a dumshit!!!! For one, wikipedia can be edited so that is a horrible way to get information. Also you can see that it is real because the fragments of rubidimium boiling in the water

ok we'll begin with the alkali metals Li Na K Rb Cs Fr. Li with 100 grams can burn up 5 litres of water in a minute.
Na 100 grams will burn up about 20 litres.
now K 100g will burn up about 40-50litres.
Rb burns more than that and this vid is fake. Cause I'm very keen about Chemistry and know more than this fools. A 100 grams will be able to burn about 500 litres of water in about 5-10 seconds.
Cs 100g will blow up about 1 megalitre in notime. And Fr more than you could ever imagine.
do you realize how stupid you sound? these guys are university profs and youre talking about how fast water burns...if you havent realized by now, this vid isnt fake and water doesnt burn. go take your "keen about chemistry" and shove it up your ass.
I've seen Rubidium (on Brainiac) being thrown into a bath full of water and it reacted very violently, in fact it blew off a huge chunk off the bath when and created a huge splash. Weird...
braniac was fake so poorly done you can see the wires for a charge also the flash of light emitted by the explosions were the wrong colour and indicated a carbon based explosive and secondly the results we saw here prove that 2g of rubidium wouldn't not blow up a bath tube i doubt a damaging explosion as shown in the braniac video would occur even in hot hydrofluoric acid

That's wrong as well, Bunsen and Kirchhoff, his assistant, worked together in spectroscopy - there is a Bunsen-Kirchhoff Award for outstanding achievements in spectroscopy, as well.
I would like to experiment with Rubidium nitrate and see what type of pyrotechnic "stars" it may produce. Potassium nitrate yields magenta colored stars, and sodium yields yellow flame. Cesium would produce purple and it would be interesting to test some rubidium. When I am finished, I will submit my report. Thanks for posting this.
If you look at one section of 3:50 section of the video, you notice that when it explodes, it shakes the container. I think that reaction wasn't horrible, when you consider the small amount there was, and the fact that 3 explosions occured. Consider how unimpressive a single gram of sodium would've been!
would've been funny if after he said "is that it?" and "don't think i needed my safety screen" if they walked towards it to retrieve the apparatus, then there was a huge rubidium explosion xD
Yeah. They should re-evaluate the effectiveness of that SMC. They don't get the "shock" effect when dropping it in 'cause most of the rubidium is covered by the glass around. Had it been dropped into the water like the potassium then perhaps most of it would explode at the same time instead of it going up in 2-3 smaller bangs as the ampule is being shattered. This goes for the cesium as well, cause I have a feeling it should've been a little more "energetic" :)
Yes, you are correct but the correct formula would probably be RbOH + H2 because hydrogen is diatomic and is only found in pairs unless combined with another element.
Both cesium and rubidium have applications in atomic physics. Also, the most interesting applications of rubidium in physics involve not incredibly hot samples like you described, but ultracold (10's of uK) clouds where the internal structure decouples from thermal averaging effects and really beautiful quantum phenomena manifest themselves.
Christians of this website, the judgement day have started already, please I urge you to depart from all form of unchristian conduct lest you be found not worthy to enter the kingdom of God. Please do not label my activity spam, I did not do it for that purpose.
No, "random persons" cannot buy metallic rubidium or any other chemical shit that is not for sale at market, of course all this i've sat i mean legally.
Sure you can. I just looked it up with a science kit chemical supply company. It is expensive and is hard to ship because it is a hazordus material. Some materials require a hazerdous material liscence but this isn't one of them. Btw its used in fireworks for the purple color.
Lol, and they call themselfs First World countries, cant fucking believe it? Can somebody really buy this stuff without documentation, here in Brazil we have to report everything to CRQ(Regional Chemical Center), there's one for every state.Without a proper registration that can only be provided for those who studied chemistry.
Strange thing...but can you afford enough quantidities of this metal?
Yeah in the us you can order it. However add the shipping cost which is robbery and you are looking at around 300 dollars a gram. I can't see why it would be illegal, if you wanted to build a bomb nitrates would be about 1000% less expensive for bang for your buck.
If it was a powder, i think the explosion would be bigger. Because now it has a small contact area with the water to produce hdrogen. poder,large contact area, more hydrogen production at the same time.
I'd rather cut off a insanely small piece of it like smaller than a bread crumb and place it on my tongue and see what would happen and also see what it would taste like.
Make sure you can go to a doctor because Rubidium Hydroxide (RbOH) is a strong basic chemical. Inhalation, ingestion or SKIN CONTACT with material may cause SEVERE INJURY or DEATH. Contact with molten substance may cause severe burns to skin and eyes. AVOID any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be CORROSIVE and/or TOXIC and cause pollution.
That was a lame experiment for Rubidium? Its soo much more reactive, what happened its reactive-ness lol. I'd like them to attempt Ceasium, in the same quanity (1 gram) it should be TOOO dangerous.
Hmm, I was just thinking, I have a feeling the reason behind the explosion being so small is because only that Rb that was near the opening in the tube reacted, then the next lots, then the next lot, maybe you could break it up under a nitrogen or argon atmosphere and then place in a small container and open that UNDER the water, so that all the metal comes in contact with the water at once, meaning faster, more explosive reaction.
The energy released increases per atom, not necessarily per mass, and since rubidium atoms (and caesium) are much larger and heavier than sodium or potassium you might not get the huge explosion you are looking for.

would've been funny if after he said "is that it?" and "don't think i needed my safety screen" if they walked towards it to retrieve the apparatus, then there was a huge rubidium explosion xD
CitizenErased2007 2 years ago 3
That is because of that glass around. I assume it didn't break properly. Theoretically Rb shoud explode a bit stronger than potassium in water.
armandbush 2 years ago
Yeah. They should re-evaluate the effectiveness of that SMC. They don't get the "shock" effect when dropping it in 'cause most of the rubidium is covered by the glass around. Had it been dropped into the water like the potassium then perhaps most of it would explode at the same time instead of it going up in 2-3 smaller bangs as the ampule is being shattered. This goes for the cesium as well, cause I have a feeling it should've been a little more "energetic" :)

sparxwil 2 years ago
yeah, our chemistry teacher told us, that it would even explode if it touched the air!
it is mostly reacting into RbOH + H
Blinkwing 2 years ago
But then what happens to that remaining hydrogen atom?
Ununennium119 2 years ago
it doesn't make a link to the RbOH, it just disappears into the atmosphere
Blinkwing 2 years ago
What do you mean by "disappear"? You must remember the conservation of mass (what you put in is what you get out, in different arrangements).
Ununennium119 2 years ago
yeah, if you would make the reaction in a locked area, you would have got RbOH and H separately
Blinkwing 2 years ago
But that still doesn't explain what happens to the hydrogen atom.
Ununennium119 2 years ago
just look at a bottle of water, and then fill some oil into it.
Now imagine, The water is the RbOH and the oil is H, you can see, that they will not mix, they stay separated
Blinkwing 2 years ago
Incorrect because Hydrogen is a diatomic element and always will form H2.
SETHHIKARU 2 years ago
damn :-S
Thats right, im sorry, hydrogen is a molekulary element, just like Cl, J, Br and some others!
yeah, i was wrong
Blinkwing 2 years ago
Yes, you are correct but the correct formula would probably be RbOH + H2 because hydrogen is diatomic and is only found in pairs unless combined with another element.
Guitartzero 2 years ago
yeah, but at first it is a single atom, but because the reaction is soo fast it would directly find a pair
Blinkwing 2 years ago
No it's never in a single atom state. It moves over to another atom then pairs up with another Hydrogen atom. Making H2 instantaneously.

Both cesium and rubidium have applications in atomic physics. Also, the most interesting applications of rubidium in physics involve not incredibly hot samples like you described, but ultracold (10's of uK) clouds where the internal structure decouples from thermal averaging effects and really beautiful quantum phenomena manifest themselves.

can any random person buy rubidium or do you have to be a scientist?

No, "random persons" cannot buy metallic rubidium or any other chemical shit that is not for sale at market, of course all this i've sat i mean legally.
Draxis32 2 years ago
Sure you can. I just looked it up with a science kit chemical supply company. It is expensive and is hard to ship because it is a hazordus material. Some materials require a hazerdous material liscence but this isn't one of them. Btw its used in fireworks for the purple color.
wormbaby79 2 years ago 2
Really?
Lol, and they call themselfs First World countries, cant fucking believe it? Can somebody really buy this stuff without documentation, here in Brazil we have to report everything to CRQ(Regional Chemical Center), there's one for every state.Without a proper registration that can only be provided for those who studied chemistry.
Strange thing...but can you afford enough quantidities of this metal?
He's a kinda rare so it will be expensive.
Draxis32 2 years ago
Yeah in the us you can order it. However add the shipping cost which is robbery and you are looking at around 300 dollars a gram. I can't see why it would be illegal, if you wanted to build a bomb nitrates would be about 1000% less expensive for bang for your buck.

invertedchords 2 years ago
If it was a powder, i think the explosion would be bigger. Because now it has a small contact area with the water to produce hdrogen. poder,large contact area, more hydrogen production at the same time.

Good luck trying to turn rubidium into powder without it exploding :V
It's pretty hard to seeing as its really reaction with air particles and the fact that it is a metal.

I'd rather cut off a insanely small piece of it like smaller than a bread crumb and place it on my tongue and see what would happen and also see what it would taste like.
SETHHIKARU 2 years ago
Make sure you can go to a doctor because Rubidium Hydroxide (RbOH) is a strong basic chemical. Inhalation, ingestion or SKIN CONTACT with material may cause SEVERE INJURY or DEATH. Contact with molten substance may cause severe burns to skin and eyes. AVOID any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be CORROSIVE and/or TOXIC and cause pollution.

GUAlliance 3 years ago 2
Hmm, I was just thinking, I have a feeling the reason behind the explosion being so small is because only that Rb that was near the opening in the tube reacted, then the next lots, then the next lot, maybe you could break it up under a nitrogen or argon atmosphere and then place in a small container and open that UNDER the water, so that all the metal comes in contact with the water at once, meaning faster, more explosive reaction.
