A) \[\text{ }\!\![\!\!\text{ Ne }\!\!]\!\!\text{ }3{{s}^{2}}3{{p}^{1}}\]
B) \[\text{ }\!\![\!\!\text{ Ne }\!\!]\!\!\text{ }3{{s}^{2}}3{{p}^{3}}\]
C) \[\text{ }\!\![\!\!\text{ Ne }\!\!]\!\!\text{ }3{{s}^{2}}3{{p}^{2}}\]
D) \[\text{ }\!\![\!\!\text{ Ne }\!\!]\!\!\text{ }3{{s}^{2}}3{{p}^{4}}\]
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, \[\text{ }\!\![\!\!\text{ Ne }\!\!]\!\!\text{ }3{{s}^{2}}3{{p}^{3}}\]has highest ionisation energy.You need to login to perform this action.
