Abstract
In this work, we compiled, evaluated, and select recommended values for use for the melting points and boiling points of the alkali metals: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Here we provide all of the measurements in the literature for melting points and boiling points of these elements along with selection of recommended values. We also compiled and evaluated vapor pressures for (just) lithium from and fitted these set of data from which the boiling point can be accurately determined and computed an enthalpy of vaporization. For values reported prior to 1990, we corrected the values to the International Temperature Scale of 1990 (ITS-90).Citation
