Amongest the elements with following electronic configurations,which one of them may have the highest ionization enthalpy?1.Ne[3s2 3p1]2.Ne[3s2 3p3]3.Ne[3s2 3p2]4.Ar[3d10 4s2 4p3]

Solution

In first three electronic configuration the 2 (.Ne[3s2 3p3]) has higher energy as ionization energy increases with increasing the no. of electron in same shell. In 2 and 4 the ionization energy is high for 2 as ionization energy decreases as new electron is added to different shell.So the 2 electronic configuration 2.Ne[3s2 3p3] has highest ionization energy.
