The universe is made up of atoms, which contain protons (positively charged particles), neutrons (particles with no charge), and electrons (negatively charged particles). ... Molecules are formed when two or more atoms bond together. If molecules contain atoms of different elements, that substance is known as a compound.

$\sim$ Atom :-

An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.

$\sim$ Molecules :-

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine. The atoms of some elements do not easily bond with other atoms. Examples are neon and argon.
