In the following, the element with the highest ionisation energy is
A)\[[Ne]3{{s}^{2}}3{{p}^{1}}\]
B)\[[Ne]3{{s}^{2}}3{{p}^{3}}\]
C) \[[Ne]3{{s}^{2}}3{{p}^{2}}\]
D) \[[Ne]3{{s}^{2}}3{{p}^{4}}\]
Correct Answer:
B
Solution :
Elements having half-filled or fully filled orbitals are more stable. Hence, much energy is required to remove an electron from the outermost orbit. So, the element with \[[Ne]3{{s}^{2}}3{{p}^{3}}\]configuration has highest ionisation energy.
