Elements X and Y have electronic configurations 1s22s22p6 and 1s22s22p63s23p1 respectively. When they combine, the formula of the compound formed is

Answer Details

$\frac{\text{Element X}}{1s^{2}2s^{2}1p^4}$

Valency of X is 2

$\frac{\text{Element Y}}{1s^{2}2s^{2}2p^{6}3s^{2}3P^1}$

valency of Y is 3

There is an exchange of valency when a compound is being formed. Hence, we have Y2X3
