Explanation:

Zn= 30

Zn2+=30-2=28

E.C.= 1s2 2s2 2p6 3s2 3p6 4s2 3d10

when ionisation is done ...then the outermost shell electrons tend to come out ....thus on applying the required ionisation enthalpy ....the 2 electrons from 4s2( outermost) come out and zn becomes zn2+ and the configuration ends at 3d10
