Question

in physics modern perodic table most reactive element is

Answer 1

It is francium. in metals it is cesium

Answer 2

Group I metals are mostly high reactive because they have only one electron in their valence shell , they get more reactive as we move down to the periodic table. As the electrons are farther from the nucleus and shielded by the inner electrons

the most reactive element is fluorine (F) and it is also electronegative in the top of the halogen group
