Characteristic
Caesium is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature.
Phase at STP：solid
Appearance：pale gold
Melting point：301.7 K (28.5 °C, 83.3 °F)
Boiling point：944 K (671 °C, 1240 °F)
Density (near r.t.)：1.93 g/cm3
when liquid (at m.p.)：1.843 g/cm3
Critical point：1938 K, 9.4 MPa
Heat of fusion：2.09 kJ/mol
Heat of vaporization：63.9 kJ/mol
Molar heat capacity：32.210 J/(mol·K)
Application
The largest application of the element has been as caesium formate for drilling fluids, but it has a range of applications in the production of electricity, in electronics, and in chemistry. The radioactive isotope caesium-137 has a half-life of about 30 years and is used in medical applications, industrial gauges, and hydrology.
