Valence electrons are the number of electrons present in the outermost shell of an atom
For example Na=(2,8,1) So Valence electron is 1 so Na will donate its 1 e- to complete its octet therefore its valency is 1 whereas S=(2,8,6) here valence electrons are 6 but it needs 2 more to make it 8 and complete octet therefore valency is 2 So valence e-= No.of e- in last shell and Valency = No. Of e- donated or accepted to complete its octet
