Positively charged protons and neutrally charged neurons form the nucleus that resides in the center of the atoms. Negatively charged electrons revolve around the nucleus is an area known as the electron cloud. The protons and neutrons have considerable mass, approximately 1 amu each. The electrons have virtually no mass.
