`O_(2)`molecules consists of two oxygen atoms. In the molecules , nuclear force between the nuclei of the two atomsA. is not important because nuclear forces are short-ranged.B. is as important as electrostatic force for binding the two atomsC. cancels the repulsive electrostatic force between the nucleiD. is not important because oxygen nucleus has equal number of neutrons and protons.

Answer» Correct Answer - A
In the given oxygen molecule, nuclear force between the nuclei of two atoms is not important because nuclear forces being short ranged are confined only within one particular. The distance between the nuclei to two atoms is large. So nuclear forces between two nuclei is not effective.
