Question

Difference between metal and nonmetal on the basis of electrochemical behaviour

Answer 1

Metals are electropositive in nature as they easily lose electrons, so they are reducing agents. On the contrary, non-metals are electronegative because they gain electrons and thus they are oxidising agents.

Answer 2

answer=

Metals have 1, 2 or 3 valence electron so they always ionize by losing electrons while non metals have 4, 5, 6 or 7 valence electron so they ionize by gaining electrons.

So, metal acts as reducing agents while non metals acts as oxidising agents.
