![]() Atomic Volume |
Atomic volume is the volume of one mole of an element in a condensed phase--one mole of a solid or a liquid. We report it in units of cm³/mol. Atomic volumes of the elements were calculated as Atomic volume = (atomic weight) / (density) The density at room temperature (25°C) was used (see DENSITY for references) except for the gaseous elements, in which case density of the liquid at the boiling point was used. Densities at the boiling point were obtained from the 81th edition of the CRC HANDBOOK OF CHEMISTRY AND PHYSICS, D. R. Lide, Ed., CRC Press, Inc., 2000. A consequence of using densities at the boiling point is that atomic volumes included in the database are not always identical with the quotient (atomic weight)/(density) calculated from the database for the same element. |
