Across
  1. 3. covalent bond in which two pairs of electrons are shared between two atoms
  2. 6. compound containing two different elements
  3. 7. distance between the nuclei of two bonded atoms at which the lowest potential energy is achieved
  4. 8. charge that would result on an atom by taking the number of valence electrons on the neutral atom and subtracting the nonbonding electrons and the number of bonds (one-half of the bonding electrons)
  5. 12. bond formed when electrons are shared between atoms
  6. 14. diagram showing lone pairs and bonding pairs of electrons in a molecule or an ion
  7. 15. situation in which one Lewis structure is insufficient to describe the bonding in a molecule and the average of multiple structures is observed
  8. 16. shape in which three outside groups are placed in a flat triangle around a central atom with 120° angles between each pair and the central atom
  9. 18. theory used to predict the bond angles in a molecule based on positioning regions of high electron density as far apart as possible to minimize electrostatic repulsion
  10. 19. bond in which a single pair of electrons is shared between two atoms
Down
  1. 1. bond in which three pairs of electrons are shared between two atoms
  2. 2. model that describes the changes in the atomic orbitals of an atom when it forms a covalent compound
  3. 4. model that describes the behavior of electrons delocalized throughout a molecule in terms of the combination of atomic wave functions
  4. 5. strong electrostatic force of attraction between cations and anions in an ionic compound
  5. 9. guideline that states main group atoms will form structures in which eight valence electrons interact with each nucleus, counting bonding electrons as interacting with both atoms connected by the bond
  6. 10. arrangement of atoms in a molecule or ion
  7. 11. shape in which four outside groups are placed around a central atom such that a three-dimensional shape is generated with four corners and 109.5° angles between each pair and the central atom
  8. 13. shape in which five outside groups are placed around a central atom such that three form a flat triangle with 120° angles between each pair and the central atom, and the other two form the apex of two pyramids, one above and one below the triangular plane
  9. 17. two (a pair of) valence electrons that are not used to form a covalent bond
  10. 19. covalent bond formed by overlap of atomic orbitals along the internuclear axis
