(a)
Interpretation:
The given set of elements has to be arranged in increasing order of atomic radius.
Concept Introduction:
The atomic radius of a chemical element is a measure of the size of its atoms, the atomic radius is distance from the centre of the nucleus to the boundary of the surrounding cloud of electrons.
The atomic radius decreases from left side to right side in the periodic table whereas atomic radius increases from top to bottom in the periodic table.
(b)
Interpretation:
The increasing atomic radius of the element should be identified.
