  1. 2. Three dimensional arrangement of a nucles atoms in space.
  2. 3. Most chemical bonding is neither purely ionic nor purely covalent because it depends on how strongly the atoms of each element attract electrons.
  3. 6. The power of an atom in a molecule to attract electrons to itself.
  4. 11. Mutual electrical attraction between the nuclei and valance electrons of different atoms that binds the atoms together.
  5. 13. Electronegativity is between 0.3 and 1.7
  6. 14. A ________ has 120◦
  7. 15. If _______ was absent we wouldn’t have any plastic nor breath.

  1. 1. Mixing of two or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies.
  2. 2. Determined by polarity of bonds and geometry of molecule.
  3. 4. Results from the sharing of electron pairs between two atoms.
  4. 5. Orbitals of equal energy produced by combination of two or more orbitals on the same atom.
  5. 7. If _______ was absent we wouldn’t have any batteries.
  6. 8. Chemical bonding that results from the electrical attraction between cations and anions.
  7. 9. A _____ has 109◦
  8. 10. Electronegativity is less than 0.3
  9. 12. A ______ has 104.5◦
  10. 16. Theory which states that repulsion between the sets of valance- level electrons surrounding an atom causes these sets to be oriented as far apart as possible.
