What is the valency of carbon in CH4 ?
In CH4, carbon has a valency 4 and hydrogen has a valency 1. So by crossing over, we get this chemical formula.
What is the valency of :
(a) fluorine in CaF2 (b) sulphur in SF6
(c) phosphorus in PH3 (d) carbon in CH4
An element has the electronic configuration 1s2,2s2 2p6,3s2 3p2. Its valency electrons are
