Answer:
As you can seen the first 4 ionization energies increases slightly then there is a jump.This means that X and Y have 4 valences >> group IVA
X has higter ionization energies so X is over Y in the group.
I thing X is C and Y is Si
X is a Gr 1 (Alkali) and Y is a Group 3 or Aluminium group metal.
