If first ionization enthalpies of elements X and Y are $\displaystyle 419 \mathrm{~kJ} \mathrm{~mol}^{-1}$ and $\displaystyle 590 \mathrm{~kJ} \mathrm{~mol}^{-1}$, respectively and second ionization enthalpies of X and Y are $\displaystyle 3069 \mathrm{~kJ} \mathrm{~mol}^{-1}$ and $\displaystyle 1145 \mathrm{~kJ} \mathrm{~mol}^{-1}$, respectively. Then correct statement is :
