  1. 2. structures/ formulas in which atomic symbols represent nuclei and inner-shell electrons, dot-pairs or dashes between two atomic symbols represent electron paris in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electrons
  2. 3. covalent bond/ a bond formed by sharing three pairs of electrons
  3. 5. bonding/ the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
  4. 6. numbers/ Shows how many electrons can be shared, lost or gained to become stable; you cancel out the valence numbers to make the compound
  5. 7. ions/ They consist of a single atom with a positive or negative charge resulting from the loss or gain of electrons.
  6. 10. compound/ a compound that consists of positive and negative ions
  7. 12. polarity/ the uneven distribution of molecular charge
  8. 13. formula/ a representation of a substance using symbols for its constituent elements
  9. 17. covalent bond/ a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
  10. 18. bonding/ the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule
  11. 20. covalent bond/ a bond in which two atoms share two pairs of electrons
Down
  1. 1. covalent bond/ a covalent bond in which electrons are not shared equally
  2. 4. ions/ ions that are made of more than one atom
  3. 8. the simplest structural unit of an element or compound
  4. 9. formula/ a chemical formula showing the ratio of elements in a compound rather than the total number of atoms
  5. 11. covalent bond/ a bond formed when two atoms share a pair of electrons
  6. 13. bonding/ results from the sharing of electron pairs between two atoms
  7. 14. valence/ atoms gain more than 8 valence electrons
  8. 15. molecular compounds/ Non metal and a non metal has charges in the name
  9. 16. unit/ the simplest collection of atoms from which an ionic compound's formula can be established
  10. 19. energy/ the energy required to break a chemical bond and form neutral isolated atoms
