Question

O₂ molecule consists of two oxygen atoms. In the molecule, nuclear force between the nuclei of the two atoms(a) is not important because nuclear forces are short–ranged(b) is as important as electrostatic force for binding the two atoms(c) cancels the repulsive electrostatic force between the nuclei(d) is not important because oxygen nucleus have equal number of neutrons and protons

Answer 1

The nuclear force between the nuclei of two atoms is not very important because nuclear forces are short ranged and confined only with in one particular nuclear.

But the distance between the nuclei of two atoms may be large.

So the nuclear force between two nuclei may not be effective.
