Answer :

Final answer:

Describing bond formation in O2, defining nuclear energy, and explaining the nuclear reaction in the sun.


Explanation:

Bond Formation in O2 Molecules: Oxygen molecules form covalent bonds where each oxygen atom shares two electrons, resulting in a double bond between the two oxygen atoms.

Nuclear Energy: Nuclear energy is the energy released during nuclear reactions, such as fission or fusion, where the nucleus of an atom is involved.

Nuclear Reaction in the Sun: The primary nuclear reaction in the sun is the fusion of hydrogen nuclei (protons) to form helium, releasing immense amounts of energy in the process.
