In a period, atom with smallest radius generally is: (A) Chalcogen (B) Halogen (C) Aerogen (D) Pnicogen

In a period on moving left to right Z text effective increases, so atomic size decreases. For inert gases, Van der waal radius is considered, so it is bigger in size as compared to halogens.

Aerogen

Pnicogen

In a period on moving left to right $Z_{effective}$ increases, so atomic size decreases. For inert gases, Van der waal radius is considered, so it is bigger in size as compared to halogens.
