Why first ionization enthalpy of chromium is lower than that of zinc.

Text Solution

Verified by Experts

First ionisation enthalpy of Cr is lower than that of zinc because in case of zinc first electron has to be removed from which fully filled orbital which is most stable so it required high energy to remove electron from it.
