Solution
The correct option is B In any period, the atomic radius increases from left to right. Atomic radius increases as we go down a group with the filling of electrons in an additional shell. Across a period, nuclear charge increases by one unit. As a result, the electrons are pulled more tightly leading to shrinking of radius as we move across the period. Hence in any period, the atomic radius decreases from left to right.
