Vedclass · Answer

(B) The electron affinity $(EA)$ generally increases across a period and decreases down a group. However,there are exceptions due to electronic configuration. For the given elements $(C, N, O, Cl)$: $1$. $Cl$ (Chlorine) has the highest electron affinity among these because it is a halogen with a high effective nuclear charge and a small size. $2$. $O$ (Oxygen) has a higher electron affinity than $C$ (Carbon) and $N$ (Nitrogen). $3$. $N$ (Nitrogen) has a very low (near zero or positive) electron affinity because it has a stable half-filled $2p^3$ subshell. $4$. Comparing $C$ and $N$,$C$ has a higher electron affinity than $N$. Thus,the correct order is $Cl > O > C > N$.

The electron affinity of the following elements can be arranged as:
