Answer 2

Answer:

Berilium (Be) has larger 3rd I.E.

Explanation:

When we compare the 1st I.E of Be and Na ,

Be has larger I.E as it has only 2 orbitals in which the force of attraction is more compared to Na which requires more energy to remove the electron whereas Na requires less energy to remove the electron as it has 3 orbitals .

When we compare the 2nd I.E of Be and Na,

Na has larger I.E as when it has undergone the 1st I.E to lose an electron, it becomes Na+ which has the electronic configuration of Ne which is more stable. The elements which are stable or have half fill orbitals needs high I.E.

When we compare the 3rd I.E of Be and Na,

Be has larger I.E as when it has undergone the 2nd I.E to remove 1 more electron it becomes Be+2 which has the electronic configuration of He which is more stable. Hence need more I.E.
