Vedclass · Answer

(B) The correct answer is $B$. $1$. The ionisation potential of $N$ $(2s^2 2p^3)$ is greater than $O$ $(2s^2 2p^4)$ due to the stable half-filled $p$-orbital configuration. $2$. The electron affinity of $F$ is lower than that of $Cl$ because the small size of $F$ leads to strong inter-electronic repulsions,making it harder to add an electron compared to $Cl$. $3$. The ionisation potential of $Be$ $(2s^2)$ is greater than $B$ $(2s^2 2p^1)$ due to the stable fully-filled $s$-orbital. $4$. The electronegativity of $F$ is greater than $Cl$ due to its smaller atomic size.
