Provides a quantitative indication of an elements reactivity and is based on the charge of the valence electrons and the ionic radius. It is determined by the equation: (-eV) = kn/r. 'k' is a proportionality factor converting Ångstroms into centimeters and expressing the force exerted by the valence electrons in electron volts which is equated to 14.399. 'n' is the valence. 'r' is the ionic radius in Ångstroms.
The pressure exerted when a material in its solid or liquid state is in equilibrium with it's gas state. As this is changes as a function of temperature, vapor pressure must be qualified by the relevant temperature.
Readily passing into the gas state at a relatively low temperature.
The tendency of a material to pass into the gas state at a particular temperature from a solid or liquid state.
The measurement of anything in 3-demension (cubic magnitude).
