# If an element X has a valency of 3, then find out the formula of its chloride and sulphide.

Answer :

It is given that element X has a valency of 3.

__Formula__ __for chloride of element X:__

Formula: MCl_{3}

__Thus, the formula for chloride of element X is MCl _{3}.__

__Formula__ __for sulphide of element X:__

Formula: M_{2}S_{3}

__Thus, the formula for sulphide of element X is M _{2}S_{3}.__
