Chemistry 2000 JAMB Past Questions - Question 14: The distance between the nuclei of chlorine atoms in a chlorine molecule is 0.194 mm. The atomic radius of chlorine atom is

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.
