  13. 28. Element with the symbol K
  14. 30. ___________ change, where the shape or form changes but the original substance stays the same
  15. 33. Exception to the rule, has 2 valence electrons despite being in group 18.
  16. 34. A solution that contains the maximum amount of dissolved solute that a solution can hold.
  17. 38. The length of time it takes for a certain amount of solute to dissolve in a solution.

  19. 40. A liquid in which another substance is dissolved in
  20. 42. The measure of how much exposed area that a solid object has, the total area of surface of an object
  21. 43. one or more of the same type of atom
  22. 44. A chemical equation that starts and ends with the same amount of atoms
Down
  1. 1. Molecules in a chemical equation that are after the arrow
  2. 2. more than one atom bonded together
  3. 3. Put into motion by swirling, shaking, or stirring
  4. 4. The process of reducing the concentration of solute in a solution by adding more solvent.
  5. 6. These are the same as the period number
  6. 7. An element that has 3 energy levels and 4 valence electrons
  7. 8. the small letters after an element that tell you how many atoms of it are found in a molecule
  8. 10. When more solute can be added into a solvent and has the ability to still be dissolved
  9. 12. ________________ mixture. A mixture in which the concentration IS uniform
