Question

An element 'x' has a valency 2. Write (derive) simplest formula for chloride and oxide of the element​.​

Answer 1

Explanation:

Valency of X=2

Valency of Oxygen =2

X O(Oxide)

2 2

Formula for oxide of elements x can be worked out by crossing the Valencies of the constituent element

Therefore ,Formula for oxide of X is XO

Same here

Valency of X=2

Valency of chlorine =1

X Cl

2 1

Formula for chloride of elements x can be worked out by crossing the Valencies of the constituent element

Therefore, Formula for chloride of X is XCl2
