Atom is the basic unit of a chemical element. An electron is the negative charge in every atom. A proton is the positive charge of every atom. A neutron is neutral.

An atom is the building block of all matter. Electrons, protons and neutrons make up the atom. protons and neutrons make up the nucleus of the atom, and the electrons are on the electron shell.
