8.2 In the series to the enthalpy of atomisation of zinc is the lowest, i.e., . Why?
The enthalpy of atomisation of zinc is lowest due to the absence of an unpaired electron, which is responsible for metallic bonding in the elements. Therefore, the inter-atomic bonding is weak in zinc(). Hence it has a low enthalpy of atomisation.
