Across
  1. 8. an electron configuration notation in which only the valence electrons of an atom of a particular element are shown, indicated by dots placed around the elements symbol
  2. 9. indicates the kind, number, arrangement, and bonds but not the unshared pairs of the atoms in a molecule
  3. 10. shows the types and numbers of atoms combined in a single molecule of a molecular compound
  4. 15. results from the sharing of electron pairs between two atoms
  5. 16. the ability of a substance to be drawn, pulled, or extended through a small opening to produce a wire
  6. 18. indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols numerical substances
  7. 19. refers to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
  8. 20. the energy required to break a chemical bond and form neutral isolated atoms
  9. 22. uneven distrbution of charge
  10. 23. formulas in which atomuc symbols represent nuclei and inner-shell electrons, dot-pairs or dashes between tow atomic symbols represent electron pairs in covalent bonds, and dots adjacent to only one atomic symbol represent unshared electrons
  11. 24. Mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together
Down
  1. 1. the ability of a substance to be hammered or beaten into thin sheets
  2. 2. Chemical bonding that results from electrical attraction between cations and anions
  3. 3. a chemical compound whose simpliest units are molecules
  4. 4. the simplest collection of atoms from which an ionic compound's formula can be written
  5. 5. a charged group of covalently bonded atoms
  6. 6. composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
  7. 7. the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
  8. 11. a neutral group of atoms that are held together by covalent bonds
  9. 12. energy the energy released when one mole of an ionic crystalline compound is formed from gaseous ions
  10. 13. double or triple bonds, or multiple covalent bonds. Greater bond energy and are shorter than single bonds
  11. 14. a covalent bond in which one pair of electrons is shared between two atoms
  12. 17. a covalent bond with unequal attraction for the shared electons
  13. 21. a covalent bond in which electrons are shared equally, balanced distribution of electrical charge
