`color{green}(โข)` A molecule is in general a group of two or more atoms that are chemically bonded together, that is, tightly held together by attractive forces.
`color{green}(โข)` A molecule can be defined as the smallest particle of an element or a compound that is capable of an independent existence and shows all the properties of that substance.
`color{green}(โข)` Atoms of the same element or of different elements can join together to form molecules.

`color{green}(โข)` The molecules of an element are constituted by the same type of atoms.
`color{green}(โข)` Molecules of many elements, such as argon (Ar), helium (He) etc. are made up of only one atom of that element.
`color{green}(โข)` But the case is different with most of the nonmetals. For example, a molecule of oxygen consists of two atoms of oxygen and hence it is known as a diatomic molecule, `color{red}(O_2)`. If 3 atoms of oxygen unite into a molecule, instead of the usual 2, we get ozone.
`color{green}(โข)` The number of atoms constituting a molecule is known as its `color{red}("๐๐ญ๐จ๐ฆ๐ข๐๐ข๐ญ๐ฒ")`.

Atoms of different elements join together in definite proportions to form molecules of compounds.
