Question

Write the molecular formula for oxygen when the oxygen molecules consist of two oxygen atoms.

Answer 1

Answer:

Molecular oxygen (O2) is a diatomic molecule that is composed of two oxygen atoms held together by a covalent bond.

...

Properties.

Chemical formula = O2

Melting Point = −219°C

Answer 2

Answer:

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.
