  2. 5. The main type of bonding in metals
  3. 6. A molecule with 3 bonding pairs and 1 lone pair has this shape
  4. 7. these have greater repulsion than the other type of electron pairs
  5. 10. The angle in a tetrahedral molecule
  6. 11. The attraction between oppositely charged ions
  7. 12. The angle in a trigonal planar molecule
  8. 14. A specific type of strong intermolecular force involving hydrogen bonded to N, O, or F
