1.	Amongst the following elements whose electronic configuration are given below, the one having the highest ionisation enthalpy isA. `[Ne] 3s^(2) 3p^(1)`B. `[Ne] 3s^(2) 3p^(3)`C. `[Ne] 3s^(2) 3p^(2)`D. `[Ar] 3d^(10) 4s^(2) 4p^(3)`
Answer» Correct Answer - A::D (b) and (d) have exactly half -filled 3p orbitals but (b) is smaller in size than (d) . Hence ,(b) has higest ionization enthalpy.
