What is Valency?, I mean by it that the valency is termed as number of electrons an atom can give or take. But the valency of Iron(II) (Fe) is 2, and valency of Iron(III) (Fe) is 3,But why the valency of iron should be 2,8,8,8 thats in last ring it can give 8 electron so 8 should be valency. And how do we find valencies of compounds and elements i amnot clear in that. please help me. Thanks in advance.
