Actually the valency of x...whose formula of oxide is XO will be +2....{as it has 2 electrons in its outermost shell...to gain stability it have to donate its 2 electrons}
&
the valency of y.....whose formula of oxide is Y2O3 will be+3 {as it has 3 electrons in its outermost shell...to gain stability it have to donate its 3 electrons}
