People who work in nuclear power station may be exposed to Caesium, otherwise there is no health risk associated with Caesium.

It is used as Caesium formate (anion derived from formic acid) for drilling fluids.ĭue to its high reactivity, Caesium is considered as a hazardous metal.

Caesium and rubidium are used as a carbonate to manufacture high quality glass because they reduce electrical conductivity and improve stability.

It is used in medical field to treat various types of cancer.

Caesiums-137 is radioactive isotope used as a gamma –emitter in various industrial application.

It is used in the catalytic conversion of sulfur dioxide into sulfur trioxide.

Caesium is used in molecular biology for density gradient ultracentrifugation.

Caesium vapor is used in making magnetometers.

Caesium salts are used in water treatment and making mineral water.

And it also used to determine the fundamental unit of time.

Caesium is also used in the manufacturing of infrared lamps.

Caesium is widely used in the production of electricity, electronics and in chemistry.

Caesium nitrate is used to make optical glasses.

Caesium is used in industries as a catalyst promoter.

Caesium compounds with chlorides are used in photoelectric cells.

Caesium is used in vacuum tubes as a “getter” to clean the traces of oxygen and other gases when sealed.

It react with halogens and forms fluoride, chloride, bromide and iodide. Caesium hydroxides is a strong base which can attack glass. Caesium burns readily to form superoxide. It is difficult to handle Caesium because it reacts spontaneously and react with air.

Salts are hygroscopic in nature (attracting and holding water from surrounding). Double salts are less soluble but others like phosphate, acetate, carbonate are water soluble. Its salts are usually colorless unless anion itself is colored. In compounds it is present as Cs+ and binds ionically with anions. Caesium can be handled only under an inert gas, such as argon. Caesium resembles rubidium in its chemical characteristics. It reacts with water vigorously and explosively, even at low temperatures. Chemical CharacteristicsĬaesium is very reactive and pyrophoric (ignites spontaneously in air). Caesium atomic number is 55 and its atomic mass is 132.90 g/mol. Its golden color is due to decreasing frequency of light that is why it partially absorbs violet light while other colors are reflected hence it appears yellowish or golden in color. It has the melting point of 28.5 oC and also has a low boiling point 641 oC. In the presence of mineral oil it loses its metallic luster. Its physical properties are similar with rubidium and potassium. In periodic table it belongs to alkaline elements. Caesium is one of four elements who exist in liquid form at or near room temperature. Physical CharacteristicsĬaesium is a silvery-gold metallic element. The abundance of Caesium on the earth crust is about 3 part per million and it is the 50 th most common element in the earth crust. It is mostly present with rubidium in nature and other alkali metals. Cesium Periodic Table ClassificationĬaesium occurs in minute quantity in earth crust in the form of minerals like pollucite (zeolite mineral Caesium ore). They also derived its name from Latin caesius ‘’sky-blue’’ due to the formation of unique blue lines in the emission spectrum. History and DiscoveryĬaesium is considered the first element who was discovered spectroscopically in 1860 by Robert Bunsen and Gustav Kirchhoff.

It forms alloys with alkali metals, gold and mercury. It is outstanding in keeping time with precision, so it is used in atomic clocks.

Caesium, also spelt as Cesium, was discovered in 1860.
