Vedclass · Answer

(C) The enthalpy of atomization depends on the strength of metallic bonding. In $s$-block and $p$-block elements,the metallic bond strength generally decreases down a group due to an increase in atomic size,leading to a decrease in the enthalpy of atomization. However,for $d$-block elements (transition metals),the enthalpy of atomization generally increases down a group because the $d$-orbitals become more involved in metallic bonding as the principal quantum number increases,leading to stronger metallic bonds. Therefore,the statement that the enthalpy of atomization decreases down a group in $d$-block elements is incorrect.
