Vedclass · Answer

(D) In a period,as we move from left to right,the atomic radius generally decreases due to an increase in effective nuclear charge.For the elements $Si$,$P$,$Cl$,and $Ar$ belonging to the $3^{rd}$ period,the atomic radius decreases from $Si$ to $Cl$.However,$Ar$ is a noble gas and its atomic radius is measured as the van der Waals radius,which is significantly larger than the covalent radii of the other elements in the same period.Therefore,among the given options,$Cl$ has the smallest atomic radius.

Identify the element having the smallest atomic radius from the following:
