  1. 2. The study of atoms, how atoms interact with one another, and the changes associated with that interaction.
  2. 3. Anything made of atoms, has mass, and takes up space.
  3. 4. chemistry The branch of chemistry where the theories and techniques of physics are applied to chemistry.
  4. 5. property Any property that describes the physical state of a substance. Can be observed without a chemical change occurring.
  5. 9. change A change in the chemical composition of a substance. EX: Burning, rusting, exploding.

  1. 1. A substance made of only one type of atoms. Ex: Pure gold
  2. 2. property A property that describes a characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction.
  3. 4. change Any change in the physical state of a substance without altering the chemical composition of that substance. EX: melting, freezing, tearing, crushing, etc.
  4. 6. property A property that does NOT depend on the amount of a substance being measured. If the amount of the substance changes, its intensive properties will NOT change. Ex: density, color, etc.
  5. 7. The smallest unit of matter. It cannot be broken down further without a nuclear change occurring.
  6. 8. The study of the chemical processes that take place in living organisms.
  7. 10. property A property that depends on how much of a substance is being measured. If the amount of the substance changes, its extensive properties will change. Ex: Mass, Volume, etc.
  8. 11. A substance made of two or more different types of atoms bonded together.
