Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).

Valency is the ability of an atom to make sharing with others for example the carbon has valency 4, it is tetrahdral can combine with 4 bonds to other one so Phosphorus has valence number 3 &5 because it can make PCl3, PCl5 simultaniously.
