Atom | The smallest particle of an element; made of electrons protons, and neutrons. |
Atomic Mass | The mass of an atom, approximately equal to the number of protons and neutrons in the atom. |
Electrical Charge | A property of matter determined by the number of positively charged protons and negatively charged materials in a material. |
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 atom. |
Nucleus | The tiny, very dense, positively charged region in the center of an atom that is made up of protons and neutrons. |
Proton | A positively charged subatomic particle located in the nucleus of an atom; contributes to the mass of the atom. |
Subatomic Particles | Particles that are smaller than the atom. |
