Answer:
A. potassium
Explanation:
Potassium is expected to have the greater atomic radius from the given choices of element.
Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid states of metals.
- Across a period, the atomic radii decreases progressively from left to right.
- This is due to the progressive increase in the nuclear charge without increase in the number of electronic shells.
