Caesium reacting with water brainiac dating, welcome to lectures for life
But why are these 3 elements so differently colored? Alkali metals[ edit ] It is a well known fact that alkali metals lithium to cesium increase in reactivity going down Group 1 of the periodic table. Therefore, while mentioning the experiment is verifiableI think including it may be giving undue weight to an isolated observation that has not been proven conclusively.
The fact that Cs III hasn't been isolated yet is quite surprising.
No more than about grammes exists on earth at any one time. Practicable, not so much.
Has it been a lie all this time that bromine is liquid at room temperature? It is by far the most interesting part, the rest is very similar to the rest of the group.
I'm sure there was a reason it was put in though, so if it can be better explained I won't object to putting it back. However, the blast would not be as large as Brainiac would make it seem.
Apart from cesium, copper, and gold, metals are blackish ot whitish silver, no? From looking at other wikipedia articles and high school science classes it seems to me that we are forgeting Bromine?
There is an account that caesium, reacting with fluorinetakes up more fluorine than it stoichiometrically should. No greenish metals appear presumably because the relativistic or overlapping-orbitals mechanisms must, to meet the requirements of the human eyetogether see to the absorption of red and blue light to reflect green and maybe that is just too rare given the availability of only odd elements to experimenters.
In fact the Ca method is what is used commercially.
Brainiac: Science Abuse
Could we use Francium in Selllafield? Thus, the higher mass metals will not produce a dramatic reaction even though the reaction is intense and these metals will readily react with water vapour in the air.
Assuming you are talking about the energy released from the Fracium reacting with water. First off it doesn't seem relevant what do Latin phonetics have to do with English pronunciation?
