lonization potential of phosphorus is gr...

lonization potential of phosphorus is greater than that of sulphur because

A

of its smaller size

B

of more penetrating power of p-orbitals.

C

its nuclear force of attraction on electrons.

D

half-filled orbitals are more stable.

Text Solution

Verified by Experts

The correct Answer is:
D
Phosphorus contains half-filled 3p orbitals, have extra stability. So, the removal of an electron from phosphorus atom requires more energy than sulphur.
