At the molecular level, how would you describe O2?

Answer 1

O2, or molecular oxygen, is a diatomic molecule consisting of two oxygen atoms bonded together by a covalent bond. The two atoms share a total of four electrons, two from each atom, to form the bond. The molecule has a linear shape and is colorless, odorless, and tasteless in its gaseous state. O2 is essential for respiration in living organisms and is involved in many chemical reactions. It is also a major component of the Earth's atmosphere.
