Question

An element X forms the following compounds with hydrogen, carbon and oxygen:
H₂X, CX₂, XO₂, XO₃
State the three valencies of element X which are illustrated by these compounds.

Open in App

Solution

Valency of X in H₂X = $-$ 2
Valency of X in CX₂ = $-$ 2
Valency of X in XO₂ = +4
Valency of X in XO₃ = +6

Hence, element X is showing three different valencies which are $-$ 2, +4 and +6.
