If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
Hydrogen fluoride is the most reactive compound in this group (not element).
A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
fluorine is the most reactive
it is because zinc is more reactive than copper. thus it can replace copper from its compound. displacement reaction is the reaction in which the more reactive element replaces the less reactive element from its compound. hence zinc is replacing copper from its compound. Obviously it is a displacement reaction.

Uranium reacts well with most nonmetals and their compound's. Very simple.
No. More reactive halogens will replace less reactive ones in a compound. This is because a more reactive halogen is more stable in a compound relative to a less reactive one, while a less reactive halogen is relatively more stable in its elemental form.

Oh yeah. So reactive, in fact, that bromine rarely exists by itself in nature; only locked up in a compound. Bromine is a halogen, group 17, and those are the most reactive of all the non-metals.

fluorine is the most reactive
It is not reactive.It is a neutral compound.
the reactivity series lists elements in order from most reactive to least reactive. in a displacement reaction, a more reactive element will "displace" a less reactive element in a compound, the reactivity series can therefore be used to determine which displacement reactions are possible.
It is not reactive.It is a neutral compound.
Argon is stable. Calcium is reactive. There is no compound that forms between argon and calcium.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
