Vedclass · Answer

(D) The first ionisation energies of $Ti$,$V$,$Cr$,and $Mn$ are $656 \ kJ/mol$,$650 \ kJ/mol$,$652 \ kJ/mol$,and $717 \ kJ/mol$ respectively.Ionisation energy generally increases from left to right in a period,although there are irregularities due to electronic configurations.Among the given elements,$Mn$ $(3d^5 4s^2)$ has a stable half-filled $d$-subshell configuration,which contributes to its higher ionisation energy.Therefore,$Mn$ has the maximum first ionisation potential.

Which of the following elements has the maximum first ionisation potential?
