Elements X and Y have electronic configurations 1s\(^2\)2s\(^2\)2p\(^4\) and 1s\(^2\)2s\(^2\)2p\(^6\)3s\(^2\)3p\(^1\) respectively. When they combine, the formula of the compound formed is
XY
X\(_2\)Y
Y\(_2\)X\(_3\)
X\(_2\)Y\(_3\)

x= 8
y= 13
x= 2 6 would gain 2
y= 2 8 3 would lose 3
therefore, x and y would exchange their digits
x X y
2 3
X3Y2
X has 6 electrons in its outermost shell which make its oxidation number to be -2(it is deficient), while Y has 3 electrons in its outermost. so for it to be balanced we have X3Y2
Sir, honestly speaking i didn't understand how X get 3 and Y get 2.
option supposed to be the correct answer, because from your explanation you said X need 2 electron to balance it outermost shell and Y give out 3 electron.
