Intermolecular Forces
Attractive forces that occur between molecules.
Intramolecular Forces
Attractive forces that occur between atoms in a molecule; chemical bonds.
Dipole-Dipole Attraction
Attractive force between the positively charged end of one molecule with the negatively charged end of another polar molecule.
Hydrogen Bonding
Special name for unusually strong dipole-dipole attractions that occur among molecules in which hydrogen is bonded to a highly electronegative atom(such as nitrogen, oxygen, or fluorine).
London Dispersion Forces
Relatively weak intermolecular forces resulting from a temporarily uneven distribution of electrons that induces a dipole in a neighbor. Instantaneous dipole forces for non polar molecules
Normal Boiling Point
The boiling temperature of a liquid under one atmosphere of pressure. The temperature at which the vapor pressure of a liquid is exactly one atmosphere.
Heating/Cooling Curve
Normal Freezing Point
The freezing temperature of a liquid under one atmosphere of pressure.
Molar Heat of Fusion
The energy required to melt one mole of a solid.
Molar Heat of Vaporization
The energy required to vaporize one mole of a liquid.
Vaporization (evaporation)
The process in which a liquid is converted to a gas.
Condensation
The process in which a vapor is converted to a liquid.
Vapor Pressure
The pressure exerted by a vapor in equilibrium with its liquid phase at a certain temperature.
Crystalline solids
A solid characterized by the regular arrangement of its components.
Ionic Solids
A solid that contains cations and anions.
Does not conduct as a solid but does as a liquid
Kbr, AgNO3, Cs2O are examples of.
Molecular Solids
A solid composed of molecules.
type of solid with very low melting points
SO2, N2, PCl3 are examples
Atomic Solids
A solid that contains atoms at the lattice points.
Electron Sea Model
Pictures a regular array of metal atoms in a "sea" of valence electrons that are shared among the atoms in a nondirectional way and that are quite mobile in the metal crystal.
Alloy
A substance that contains a mixture of elements and has metallic properties.
Substitutional Alloy
Some of the host metal atoms are replaced by other metal atoms of similar sizes.
Interstitial Alloy
Formed when some of the interstices (holes) among the closely packed metal atoms are occupied by atoms much smaller than the host atoms.
metals
Zr, Ba, Pb are examples of
Covalent network solids
diamond and quartz are examples of
