Answer:

Beryllium (Group II) has an extra electron and proton compared with lithium. The extra electron goes into the same 2s orbital. The increase in ionisation energy (I.E.) ... Similarly, the I.E. of Oxygen is less than that of Nitrogen because the extra electron is shielded by the half-filled 2p orbital.
