Periodic Classification and Periodic Properties 2 Question 22
22. The first ionisation potential in electron volts of nitrogen and oxygen atoms are 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: 22. $(\mathrm{a}, \mathrm{b})$
Solution:
- First ionisation energy of oxygen is less than that of nitrogen on the ground of stability of valence shell configuration, hence (a) is the correct answer.
