Question

an element X belongs IV A. what would be its valency ? write the formulae of the molecules of compound it will form with element Y belonging to group lll A and with element it Z belonging to VIl A.​

Answer 1

Answer: it belongs to group IV A so its valency is 4

For example carbon

Explanation:

It will become X3Y4 like situation because elements of III A has a valency of 3 for example aluminium

If it forms bond with elements of group VIIA for example chlorine the situation becomes like this XZ4

Now 1 example for each bond formation

For example if aluminum reacts with carbon Al4C3

For example if chlorine bonds with carbon CCl4
