Metals are elements, such as Iron (an element) and Copper (also an element), and they react for various reasons.
A reactive non metal is an element that can gain the electrons or is more electronegative
A reactive non-metal.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
If it is a metal it is a reactive element.
There are many examples. Ni is a example element.
Fluroine is the most reactive non-metal.
No. Potassium metal is to reactive and expensive for everyday use.
The most reactive metal is is francium, though cesium is often given this title due to francium's extreme rarity and short half life. The most reactive element is commonly said to be fluorine. But fluorine is a nonmetal.
A more reactive metal pushes out a less reactive metal out of a compound element, eg. CuSo4+Mg=MgSo4+Cu
fluorine
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
