Correct Answer
A
Explanation
To find the atomic radius of a chlorine atom, we can use the given distance between the nuclei of chlorine atoms in a chlorine molecule, which is 0.194 nm (not mm, as it's a very large distance for atomic scale).
The atomic radius of a chlorine atom can be calculated using the formula:
Atomic radius = (Distance between nuclei) / 2
Plugging in the given distance:
Atomic radius = 0.194 nm / 2
Atomic radius = 0.097 nm
So, the atomic radius of a chlorine atom is 0.097 nanometers.
