Radioactive - The atoms decay over time and emit radiation. Isotope - The same number of protons, but a different number of Neutrons. Ionized - The number of electronic do not equal the number of protons. Atom - The basic unit of a chemical element. Atomic number - the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. Electron - a stable subatomic particle with a charge of nega...
