  1. 3. ions ions that are made of more than one atom
  2. 4. solids a substance in which all of the atoms are covalently bonded to each other
  3. 6. angle the angle formed by two bonds to the same atom
  4. 7. consisting of two atoms
  5. 11. number the positive or negative charge of a monatomic ion
  6. 12. atom an atom that is located at the end of a molecule or chain
  7. 13. Valence Shell Electron Pair Repulsion
  8. 14. Compounds Created by the unequal sharing of electrons. The result is a molecule with a positive end and a negative end. (Ex: water)
  9. 15. formula Symbols that show the elements in a compound and the ratio of atoms
  10. 18. A substance made up of atoms of two or more different elements joined by chemical bonds
  11. 20. Shell Electron Pair Repulsion (VSEPR) Theory each atom in a molecule will move to achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. (they will spread out as far as possible)
  12. 21. structure A structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds.
  13. 22. der Waals/ London dispersion forces All molecules/compounds have these, temporary dipoles created when electrons move to one side of the atom

  1. 1. A very large organic molecule composed of many smaller molecules
  2. 2. attractions between oppositely charged regions of polar molecules
  3. 5. rule States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
  4. 8. forces forces of attraction between molecules
  5. 9. Compounds a compound whose electrons are equally distributed among its atoms (Ex: Oil)
  6. 10. bonds attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom
  7. 15. atom Atom covalently bonded to one or more atoms in a molecule. The electrons on the central atom determine the shape of the molecule. The least electronegative element
  8. 16. bond a bond formed by the attraction between positively charged metal ions and the electrons around them
  9. 17. pair electrons Unbonded electrons that are paired up in an orbital and are not part of a covalent bond
  10. 18. bond A chemical bond that involves sharing a pair of electrons between atoms in a molecule
  11. 19. bond A chemical bond resulting from the attraction between oppositely charged ions.
