  1. 5. A covalent bond in which the bonded atoms have an unequal attraction for the shared electrons
  2. 7. A bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
  3. 8. Results from the Sharing of electron pairs between 2 atoms
  4. 12. Uneven distribution of charges
  5. 13. Types and numbers of atoms combined in a single molecule of a molecular compound
  6. 15. Chemical Bonding that results from the electrical attraction between cations and anions
  7. 16. The energy required to break a chemical bond and form neutral isolated atoms
Down
  1. 1. A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds atoms together
  2. 2. combined so that the numbers of positive and negative charges are equal
  3. 3. Multiple covalent bonds
  4. 4. Indicates relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts
  5. 6. A chemical compound whose simplest units are molecules
  6. 9. the simplest collection of atoms from which an ionic compound’s formula can be written
  7. 10. A Neutral Group of atoms that are held together by covalent bonds
  8. 11. A charged group of covalently bonded atoms
  9. 14. a covalent bond in which one pair of electrons is shared between two atoms
