$Cr, Cu$

Vedclass · Answer

(A) The first ionization enthalpy of $Cr$ $(3d^5 4s^1)$ is higher than its neighbors because of the stable half-filled $d$-orbital configuration. Similarly,$Cu$ $(3d^{10} 4s^1)$ has a higher ionization enthalpy than its neighbors due to the stable fully-filled $d$-orbital configuration. Therefore,$Cr$ and $Cu$ exhibit higher ionization enthalpy values compared to their neighboring elements.

Which elements of the first transition series have higher ionization enthalpy values than their neighboring elements?
