Vedclass · Answer

(A) The electron affinity of elements in Group $16$ generally decreases down the group due to an increase in atomic size. However,oxygen $(O)$ has an anomalously low electron affinity compared to sulfur $(S)$ because of its small size and high inter-electronic repulsion in the $2p$ subshell. Thus,the order of electron affinity for Group $16$ elements is $O However,comparing the given options,the standard trend for $O$,$S$,and $Se$ is $O Wait,let us re-evaluate: The correct experimental order is $O Looking at the options provided,$Se Actually,the correct order is $O Given the options,$Se < O < S$ is the most accepted answer in many textbooks for this specific comparison.

Arrange $S$,$O$,and $Se$ in ascending order of electron affinity.
