RRB Group D (Level-1 posts) 2022 · Question 4 of 598

As atomic number increases and nuclear charge increases, the force of attraction between nucleus and valence electrons increases, hence atomic radii decreases from Li to F.

Answer: B. increases, increases, increases, decreases

With increasing atomic number across a period, nuclear charge increases, pulling electrons closer and reducing atomic radii.
