Based on the group valency of elements write the molecular formula of the following compounds giving justification for each :
Compound formed when an element, A of group 2 combines with an element B of group seventeen.

Text Solution

Verified by Experts

The correct Answer is:
`AB_2` - Valency of element A of group 2 is 2 and of element B of group seventeen is 1.
Valency of group 2 elements is 2.
Valency of group 17 elements is 1.

So, the molecular formula is `AB_2`.
