Vedclass · Answer

(C) The trends for the first four elements of group-$17$ $(F, Cl, Br, I)$ are as follows:$1$. Covalent radius: $F $2$. Electron affinity: $Cl > F > Br > I$ (Irregular,as $F$ has lower electron affinity than $Cl$ due to small size and inter-electronic repulsion).$3$. Ionic radius: $F^- $4$. First ionization energy: $F > Cl > Br > I$ (Regular trend).Thus,only electron affinity shows an irregularity in the expected periodic trend.
