Q) 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: (a) X with nitrogen. (b) X with oxygen.?

Ans: X will have a valancy of +1.

An example of XH could be NaH (Sodium Hydride where Na has a valency of +1 and H has a valency of -1).

Formula of X with nitrogen is X3N (that is 3 X and 1 N).

Formula of X with oxygen is X2O (that is 2 X and 1 O).
