Vedclass · Answer

(A) Across a period,the atomic radius decreases from left to right due to an increase in effective nuclear charge.Down a group,the atomic radius increases due to the addition of new shells.Comparing the elements:$C$ and $O$ and $F$ are in the $2^{nd}$ period. Their order of size is $F $Cl$ and $Br$ are in the $3^{rd}$ and $4^{th}$ periods respectively,so they are larger than the $2^{nd}$ period elements.The order is $F < O < C < Cl < Br$.

What is the increasing order of atomic radii for $O, C, F, Cl,$ and $Br$?
