  1. 1. The smallest fundamental unit of matter that retains the chemical properties of a specific substance
  2. 4. A positively charged subatomic particle found in the nucleus of an atom, the mass is 1 atomic mass unit (amu); determines the identity of an element
  3. 7. An ion that has a positive charge
  4. 8. a negatively charged subatomic particle that can be either free (not attached to any atom) or bound to the nucleus of an atom and has negligible mass; determines the chemical reactivity of an element
  5. 11. the system of electrons surrounding the nucleus of an atom
  6. 12. A non-charged (neutral) subatomic particle found in the nucleus of an atom, the mass is 1 atomic mass unit (amu); determines the isotope of an element

  1. 2. The smallest particle of an element that retains all the properties of that element; is electrically neutral, spherically shaped, and composed of electrons, protons, and neutrons
  2. 3. Atom An atom that has no net electrical charge
  3. 5. A mathematical wave function that describes the wave-like behavior of an electron in an atom or molecule
  4. 6. a pure substance that is made up of one type of atom
  5. 9. The positively charged center of an atom, composed of neutrons and protons, and possessing most of the mass but occupying only a small fraction of the volume of the atom
  6. 10. An ion that has a negative charge
