A molecule is a group of two or more atoms that are chemically bonded together, held tightly by attractive forces. It is formed when atoms of the same or different elements join together through chemical bonds.
Atomicity refers to the number of atoms that constitute a molecule. For example, the atomicity of oxygen gas (O2) is 2, while that of ozone (O3) is 3.
Oxygen (O2) exists as a diatomic molecule, meaning it consists of two atoms of oxygen bonded together.
