Vedclass · Answer

(A) The ionization potential $(I.P.)$ is the energy required to remove the most loosely bound electron from an isolated gaseous atom.Among the given elements,Lithium $(Li)$ is an alkali metal with a large atomic size and low effective nuclear charge,making it easiest to remove its valence electron.The $I.P.$ values are approximately: $Li \approx 5.4 \ eV$,$He \approx 24.6 \ eV$,$N \approx 14.5 \ eV$,and $Zn \approx 9.4 \ eV$.Therefore,$Li$ has the least ionization potential.

Which of the following has the least ionization potential?
