Exam 1

Chemistry II

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"
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
