Q. The correct order of ionisation energy of $C, N, O, F$ is

KCETKCET 2009Classification of Elements and Periodicity in Properties

Solution:

Ionisation energy generally increases from left to right in a period but ionisation energy of nitrogen is greater than oxygen due to stable $p^{3}$ configuration. Hence, the order is as

$C< O< N< F$
