`O_(2)`molecules consists of two oxygen atoms. In the molecules , nuclear force between the nuclei of the two atoms

Options

A. is not important because nulear forces are short-ranged
B. is as important as electrostatic force for binding the two atoms
C. cancels the repulsive electrostatice force between the nuclei
D. is not important because oxygen nucleus have equal number of neutrons and protons

Answer

A

Explanation

In the given oxygen molecule, nuclear force between the nuclei of two atoms is not important because nuclear forces being ranged are confined only within one particular nuleaus. The distance between the nuclei of two atoms may be large. So the nuclear forces between two nuclei may not be operative/effective. Choice (a) is correct.
