Chemistry II
| Question | Answer |
|---|---|
| intermolecular force | attractive forces that exist between all molecules and atoms. |
| crystalline solids | the atoms or molecules that compose them are arranged in a well ordered three dimensional array |
| amorphous solids | the atoms that compose them have no long range order. |
| dispersion | all forces contain it |
| dipole - dipole | contain a partial negative and partial positive interaction; 2 polar molecules |
| hydrogen bond | a more specific dipole, hydrogen bonded to any one of the three most electronegative atoms (F,O,N) |
| homogeneous | "like" dissolves "like" |
| heterogeneous | |
| electro affinity | how much does the atom attract electrons |
| electronegativity | how badly does the atom "hog" electrons; the power of an atom in a molecule to attract electrons to itself |
| ionic bond | the complete transfer of valence electrons between atoms |
| non polar | |
| temporary dipole |
