The first ionisation potential of nitrog...

The first ionisation potential of nitrogen and oxygen atoms are related as follows.

A

The ionisation potential of oxygen potential of oxygen is less than the ionisation potential of nitrogen

B

the ionisation potential of nitrogen is greater than the ionisation potential of oxygen

C

The two ionisation potential values are comparable

D

The difference between the two ionisation potential is too large

Text Solution

Verified by Experts

The correct Answer is:
A, B, C

(a) and (b) are infact the same statements and both are correct. `N` has slightly greater ionisation energy than oxygen which is against periodic trend. This exception is due to completely half -filled `(2p^(3))` orbital in nitrogen that makes ionisation slightly difficult than oxygen.
(c) Also correct: Although `N` has greater first ionisation potential than oxygen, two values of ionisation potentials are comparable since they are adjacent in a period, i.e. electrons are removed from same orbit during ionisation.
(d) Incorrect- opposite to (c). of the bonded atoms which in turn has periodic trend in long form of periodic table.
