Vedclass · Answer

(A) The electronic configurations are as follows:$Pd (46): [Kr] \, 4d^{10} 5s^{0}$$Ag (47): [Kr] \, 4d^{10} 5s^{1}$$Rb (37): [Kr] \, 5s^{1}$$Y (39): [Kr] \, 4d^{1} 5s^{2}$Ionisation energy depends on the stability of the electronic configuration and the effective nuclear charge.$Pd$ has a completely filled $4d^{10}$ subshell and no electrons in the $5s$ orbital,making it highly stable.Removing an electron from the stable $4d^{10}$ configuration of $Pd$ requires the highest amount of energy compared to the others,where electrons are removed from $5s$ or $4d$ orbitals with less stability or lower effective nuclear charge.Therefore,$Pd$ has the maximum first ionisation energy.
