Question:
if the electronic configuration of carbon is 1s22s22p2 then explain that why the valency of carbon is 4
Answer:
If you see the kast shell electronic configuration, in 2s2 it has 2 electrons and in 2p2 it has another 2 electrons. Therefore, the valency is the no. of electrons an atom ca gain, lose or share so that it achieves the stable octet for its outermost shell. Here, in case of carbon it is 8-4 = 4 electrons.
