Can the element oxygen form a molecule O² . interpret why so

Yes, it can

Find the explanation below

Explanation:

A molecule is a substance made up of more than one atom. Most times, the individual atoms of elements are UNSTABLE, hence, their atoms get chemically bonded to one another to form a MOLECULE.

Oxygen is an element denoted by the symbol O. Oxygen is made up of atoms that becomes chemically joined together via covalent bonds i.e each atom of oxygen shares their valence electrons, to form OXYGEN MOLECULE (O2). Oxygen molecule is referred to as a diatomic molecule because it is made up of two of the same atoms.

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

the answer is:
