In the 3d series, the .enthalpy of atomisation of zinc is the lowest ( – InterviewSolution

1.	In the 3d series, the .enthalpy of atomisation of zinc is the lowest (126kJmol^-1). Why?
Answer» Solution :In the 3d series, zinc ALONE has no unpaired electrons arid its outer ELECTRONIC CONFIGURATION is `3d^(10)4s^2`. SO zinc has the least interatomic interaction and*weakest metallicbonding. Therefore, the ENTHALPY of ATOMISATION is the lowest for zinc.
