Caesium Element & Its 5 Vital Facts | WorldOfChemicals

Unknown facts about Caesium

Caesium Element

Caesium is a metal denoted as Cs in the periodic table with the atomic number of 55. It is one of the most reactive metal. It is found in the s-block which is because the outermost electron of Caesium is in s-orbital. Caesium is a soft, shiny-gold alkali metal which is having a melting point of 28.5 °Celsius (83.3 °Fahrenheit), which is one of five rudimentary metals that can become liquid at room temperature.

The Discovery of Caesium

Chemists such as Robert Bunsen and Gustav Kirchhoff who discovered cesium in 1860 when investigating the spectrum in mineral water. The name designated from the Latin word "caesius", which denotes "sky blue". This defines to the color of the line that the spectrum the chemists saw when they were discovering the spectrum. This, later on, tipped them of a new element caesium.

Possessions of Caesium

  • Samples of cesium are kept in sealed containers, under an inert liquid or gas or in a vacuum. The element is highly reactive that it would react with water and air.

  • Cesium instinctively ignites in the air which describes that it is pyrophoric in nature.

  • It is one of the supreme alkalines of all the elements and oxidizes explosively with water to give rise to caesium hydroxide (CsOH), which is a strong base in nature.

  • Allen scale of electronegativity indicates cesium as the most electronegative element.

  • It is drawn into fine wires because of its softer-ductile character.

  • Cesium-133 is the only one isotope of cesium that occurs naturally. Although there are numerous radioactive isotopes that have been produced.

  • Caesium atom has an electron resonance frequency of 9,192,631,770 cycles per second.

Uses of Caesium

Caesium compounds are used as a drilling fluid in the petroleum industry. Caesium compounds are commonly used to make special optical glass, manufacture vacuum tubes in which Caesium is used as a catalyst promoter. Cs-137 isotope is used in cancer treatment equipment or in radiating equipment. One of its most significant advantages is in the ‘caesium clock’ (atomic clock). These clocks are important part of the mobile phones or internet devices, and also in Global Positioning System (GPS) satellites.

Natural abundance of Caesium

Cesium is anticipated to be occurred at a large quantity of 1 to 3 parts per million on the Earth's crust, which is an average occurrence for a chemical element. It is fundamentally found in the minerals of Pollucite and Lepidolite. Pollucite is a mineral that occurs in excessive quantities at Bernic Lake which is in Canada and also in the USA which are the sources the element is formulated. Though it is commercially produced as a by-product of lithium production.

Environmental effects of Caesium

During nuclear accidents and nuclear weapons testing or by nuclear power plants, radioactive isotopes of cesium may be released into the air.

Cesium compounds are very soluble in water and soils. In soils, cesium stays in the top layers which is because it has the strong bonds to soil particles and as an effect plant roots doesn’t uptake caesium. However, radioactive cesium has a possibility to enter into plants by falling on leaves. uses cookies to ensure that we give you the best experience on our website.
