Among the elements of the 3d transition series, which element possesses the lowest enthalpy of atomi — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The enthalpy of atomization depends on the strength of metallic bonding, which correlates with the number of unpaired $d$ -electrons. Zinc ($3d^{10}$) has zero unpaired $d$ -electrons, resulting in very weak metallic bonds.
