A Compound XH is formed by combination of an element X with hydrogen. Find the valency of element X. State the formula of the compounds formed by combination of X with :
(a)Nitrogen (b) Oxygen
The given formula is XH which means the oxidation state of X is +1 and H is -1. Hence valency of both atoms is 1.
Since the valency of Nitrogen is 3 and Oxygen is 2, therefore when Nitrogen combines with hydrogen it will form X3N and when oxygen combines with X, the compound formed is X2O.
Since the valency of Nitrogen is 3 and Oxygen is 2, therefore when Nitrogen combines with hydrogen it will form X3N and when oxygen combines with X, the compound formed is X2O.
