smaller than $P$

Vedclass · Answer

(A) In the periodic table,the atomic size decreases from left to right across a period due to an increase in effective nuclear charge.$P$ (Phosphorus) belongs to group $15$,while $Cl$ (Chlorine) belongs to group $17$.Since $Cl$ is to the right of $P$ in the same period ($3$rd period),its atomic size and consequently its covalent radius will be smaller than that of $P$.

The single covalent radius of $P$ is $0.11 \ nm$. The single covalent radius of $Cl$ will be
