Electron- | A negatively charged subatomic particle located in the electron cloud; involved in the formation of chemical bonds. |
Electron cloud- | The area surrounding the nucleus of an atom where the electrons are found. |
Neutron- | A neutrally charged subatomic particle located in the nucleus of an atom; contributes to the mass of the mass. |
Nucleus- | The tiny, very dense, positively charged region in the center of an atom that is made up of protons and neutrons |
