Answer:
This question is incomplete.
Explanation:
This question is incomplete. However, the radius of one atom in a diatomic molecule can be determined by dividing the internuclear distance by two. The internuclear distance is the distance between the nucleus of one atom (in the diatomic molecule) to the nucleus of the other atom (in the diatomic molecule). Thus, since the diatomic molecule has the two similar atoms "side by side", the atomic radius (the distance between the nucleus and the outermost shell of an atom) would be half of the internuclear distance.
Hence;
Atomic radius of chlorine = 198/2
Atomic radius of chlorine = 99 pm
