Across
  1. 2. an ion of 2 or more bonded ions (PO₄) has the prefix hypo or suffixes ite or ate (usually contain oxygen)
  2. 3. (Valence shell electron Repulsion) theory that Molecules will make a shape that Spreads the Valance electrons out as far as possible.
  3. 4. change changes of a substance from solid to liquid or liquid to gas
  4. 7. vibrate but don't change position
  5. 8. When a substance gets smaller due to lowering temperature or energy.
  6. 10. flow (change position)
  7. 13. a molecule shape where there are 2 atoms bonded to a center atom at an angle
  8. 14. more collisions there are between molecules. the more heat the substance can hold.
  9. 16. of matter -. all molecules are in Motion, more motion means more heat.
  10. 18. dissolve covalent molecules but not ionic
  11. 19. a molecule shape where there are 3 bonds all pointing at a downward angle
  12. 23. burning
  13. 25. Change that affects the type of Molecule or atoms in a Substance.
  14. 26. a compound where the electrons are not shared equally Creating a molecule with a slightly positive & negative side.
  15. 28. when a substance gets larger due to rise temperature/energy
  16. 29. a compound made of 2 elements
Down
  1. 1. a molecule made with a Covalent bond that shares electrons evenly
  2. 2. Change in State, Shape, Size when the Molecules stay the same.
  3. 5. the substances coming out of a chemical reaction
  4. 6. a molecule shape where the atoms make a flat triangle
  5. 9. a molecule shape where there are 4 points
  6. 11. the measure of mass per volume (changes at different temperatures)
  7. 12. the substances going into a chemical reaction
  8. 15. a reaction that gets cold (absorbs heat)
  9. 17. dissolve both polar Molecules & non polar ionic polar covalent
  10. 20. a reaction that gives off heat
  11. 21. flow and spread out to fill its space
  12. 22. - the creation of a solid from liquids or gasses without temperature drop to freezing.
  13. 24. chemical equation a chemical formula that showing a reaction how many of each molecule or element come into and go out of a reaction
  14. 27. a molecule shape where the atoms are straight because there are 2 double bonds to a center atom
