Across
  1. 3. change from one pure substance to another by the rearrangement of atoms in a chemical reaction
  2. 5. change in state from a gas directly to a solid caused by removing energy
  3. 10. two or more chemically bonded atoms
  4. 11. fluid state of matter in which the particles are free to move but are held close to each other; has unchanging volume but changeable shape
  5. 12. change of state from a solid to a liquid at the melting point that is caused by adding energy

  15. 31. change of one element into another element by changes occurring in the nucleus of the atom
Down
  1. 1. charged atom or group of atoms caused by a charge imbalance, which is produced by an unequal number of protons and electrons
  2. 2. anything that has mass and takes up space
  3. 3. change in state from a gas to a liquid caused by removing energy
  4. 4. a rigid state of matter in which the particles align in a fixed arrangement; has an unchanging shape and volume

  15. 26. smallest neutral particle of an element that retains the characteristics of that element
  16. 27. done when a force acts on a moving object in the same or opposite direction of its motion or when energy is transferred from one object to another
  17. 29. measurement of the amount of matter in an object
  18. 30. pure substance formed by chemically combining two or more elements
