For this u have to learn electronic configuration. The electrons lying in outermost shell are the valence electron. So for finding valency u have to take care of that. When an element has 4 or less than 4 electrons in outermost shell, that represents valency of that element but when an element has more than 4 electrons, the same no. is deducted from 8 and forms valency.

eg. Hydrogen has one 1 electron in its outermost shell so its valency is 1 Nitrogen ,, 5 ,, ,, ,, (8-5 = 3) Carbon ,, 4 ,, ,, ,, 4 Oxygen ,, 6 ,, ,, (8-6 = 2) Phosphorus ,, 5 ,, ,, ,, (8-5 = 3)
