Statement-1: Third ionisation energy of phosphorous is larger than sulphur.
Statement-2: There is a larger amount of stability associated with filled s-and p-sub-shells (a noble gas electron configuration) which corresponds to having eight electrons in the valence shell of an atom or ion.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer

D

Explanation

Statement-1 is false. Electrons configuration`._16S^(2+)=1s^2 2s^2 2p^6 3s^2 3p^2 and ._15P^(2+)=1s^2 2s^2 2p^6 3s^2 3p^1`
Sulphur has higher nuclear charge and smaller size than that of phosphorus so `IE_3` of `SgtP`
`E_3(P)=2,912 kJ//mol,(S)=3,361 kJ//mol`
Statement-2 is true statement.
