Periodic Classification and Periodic Properties - Result Question 25
####22. The first ionisation potential in electron volts of nitrogen and oxygen atoms are respectively given by
$(1987,1 M)$
(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. $(a, b)$
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.
