Why is enthalpy of atomisation is the lowest for Zn in 3d series of transition elements ?

Text Solution

Verified by Experts

Zinc (Z=30) has symmetrical electronic configuration `[Ar]^(18)4s^(2)3d^(10)`. As a result d-d interactions are negligible and the metallic bonds are quite weak. The element has therefore, lowest enthalpy of atomisation (126 kJ `mol^(-1)`) in the 3d transition series of elements.
