The first ionisation energies (in 
) of four consecutive elements of the second period are given in the options. The first ionisation energy of nitrogen is
Text Solution
Verified by ExpertsB
Option has the highest ionisation energy 
among the given value hence it cannot be the 
of N. It is the I 
of ' 
'.
Option has the lowest 
. Hence, it cannot be 
of 
.
If we compare and then has higher 
then
which can be compared with I-E of 
and 
. Since nitrogen has half filled stable.
Electronic configuration so, it must have higher 
than that of oxygen. Hence, is correct answer i.e., 
is 
of nitrogen.
