Vedclass · Answer

(B) In the periodic table,as we move from left to right across a period,the effective nuclear charge increases and the atomic size decreases. $1$. Ionization Potential $(IP)$ generally increases from $B$ to $O$. $2$. Electronegativity $(EN)$ increases from $B$ to $O$ $(B=2.0, C=2.5, N=3.0, O=3.5)$. $3$. Atomic size decreases from $B$ to $O$,so the order $B $4$. Electron Affinity $(EA)$ does not follow a strictly increasing trend from $B$ to $O$ due to stable configurations (e.g.,$N$ has a half-filled $p$-orbital). Both $IP$ and $EN$ follow the increasing trend $B < C < N < O$.
