Many classifications exists: metal or nonmetals, solids or gaseous, reactive or not reactive, valency number, radioacive or not, common or rare, etc.
Magnesium is highly reactive and will react with many things. It will react with elements of the Nitrogen group, the Oxygen group and the halogens. It will also react with acids, water etc.
Caesium is an extremely reactive chemical element.
Hydrogen IS reactive
fluorine is the most reactive
reactive metals
Francium is not reactive as it is a very weak and small substance of an atom in the element. Francium is used useless things, so therefore it is not reactive.
It is inert and so has the power to preserve highly reactive substances from reacting with things. It is for this reason that the extremely reactive metal, caesium, is stored in argon.

No. Both are oxidizers- they will react with the same things, but not each other.

It is as reactive as indium. Just kidding, it is reactive. Hoe reactive, more reactive than silver, but not as reactive as tin.
