An atom is the smallest possible particle of any chemical element, which will retain its chemical properties.

An atom consists of 3 subatomic particles - electrons, protons and neutrons. Electrons have a negative charge, protons have a positive charge and neutrons have no charge.

The chemical behaviour of an atom is due to the interaction between electrons. Electrons of an atom have certain predictable electron configurations, which are determined by the quantum mechanics of electrons in the atom.
