Structure of an atom

An atom is the smallest particle of an element which take part in a chemical reaction. It may or may not exist independently.

Atom contains protons, electrons and neutrons. Protons and neutrons are present inside the nucleus. Electrons revolve around the nucleus in a particular path which is called orbit or shell.
