Question

O₂ molecule consists of two oxygen atoms. In the molecule, nuclear force between the nuclei of the two atoms.

Options

• is not important because nuclear forces are short-ranged.

• is as important as electrostatic force for binding the two atoms.

• cancels the repulsive electrostatic force between the nuclei.

• is not important because oxygen nucleus have equal number of neutrons and protons.

Answer 1

Is not important because nuclear forces are short-ranged.

Explanation:

Nuclear forces are short-ranged and in case of oxygen molecule, the distance between atoms of oxygen is larger as compared to the distance between nucleons in a nucleus. So that, the force between the nuclei of two oxygen atoms is not important as nuclear forces are short-ranged forces.
