Answer:
Potassium
Explanation:
The atom with the largest atomic radius is potassium from the given list.
The 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 nuclei in the solid metal state.
Across a period in the periodic table, atomic radii decreases progressively from left to right.
This is due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
