Periodic Classification And Periodic Properties Ques 17

The first ionisation potential in electron volts of nitrogen and oxygen atoms is respectively given by

$(1987,1 \mathrm{M})$

(a) $14.6,13.6$

(b) $13.6,14.6$

(c) $13.6,13.6$

(d) $14.6,14.6$

Show Answer

Answer:

Correct Answer: 17.$(\mathrm{a}, \mathrm{b})$

Solution:

First ionisation energy of oxygen is less than that of nitrogen due to the stability of valence shell configuration, hence (a) is the correct answer.
