An atom is the smallest uncharged particle that can take part in a chemical change. An atom contains a centrally located nucleus. The nucleus contains positively charged protons and neutral neutrons. [Protons + neutrons= nucleon number or mass number] The electrons revolve around the nucleus in fixed orbits called electron shells or energy levels.
