Molecules are defined as a combination of two or more same or different atoms bounded together.

Types of molecules are as follows:

Diatomic molecules: A molecules which is consist of only two atoms of different or same elements are called diatomic molecules. Example: O2 and CO.

Heteronuclear diatomic molecules: A molecule that composed of two atoms of the same element is called heteronuclear diatomic molecules. Example: Hydrogen (H2) and Nitrogen (N2).

Homonuclear diatomic molecule: A molecule that composed of two atoms of different elements are called homonuclear diatomic molecule. Example: Hydrochloric acid (HCl) and Hydrogen fluoride (HF).
