Down
  1. 1. a change where atoms rearrange to make new material, example would be burning wood
  2. 2. the pull of gravity on an object
  3. 5. a material that does not allow electricity to flow, molecules spread apart

  5. 8. this state of matter has molecules spread out
  6. 11. the number of protons in an atom that identifies an element
