Answer / vanita shinde
The element Y is Cl having electronic configuration 2,8,7
so to complete outer orbit and become stable it requires 1
electron
So if it accepts 1 electron from Hydrogen (1) or Na having
electronic configuration (2,8,1) then the formula becomes
XY.
This will take place only if X is element having 1
electron in its outer orbit

Answer / abhilasha
x have a capacity to take 1 electron to get stable and y
element have capacity to give one to satisfy so x become
argon and y becomr naeon and the compound become Nacl
