Vedclass · Answer

(C) The ionization potential $(I.P.)$ decreases as we move down a group in the periodic table. This is due to the increase in atomic size,which reduces the electrostatic force of attraction between the nucleus and the valence electrons. Additionally,the shielding or screening effect increases,which further decreases the ionization potential. Since potassium $(K)$ is below sodium $(Na)$ in Group $1$,its $I.P.$ must be lower than $5.48 \ eV$. The experimental value for the $I.P.$ of potassium is approximately $4.34 \ eV$.

The ionization potential of sodium is $5.48 \ eV$. The $I.P.$ of potassium is ............. $eV$
