![]() You can effortlessly find every single detail about the elements from this single Interactive Periodic table.You're listening to ASK ME ANOTHER from NPR and WNYC. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). Free Gift for you: Interactive Periodic Table Cesium compounds are also used in making special optical glasses.The compounds of cesium are used as drilling fluids in petroleum industries.Cesium is used in photoelectric cells as well as photomultiplier tubes.Cesium is used as a catalyst in the hydrogenation of organic compounds.As cesium is reactive to oxygen, it was used in vacuum tubes to remove the oxygen gas.The electronegativity of cesium is 0.79 on the Pauling scale.The first ionization energy of caesium is 3.894 eV.When cesium reacts with water, it forms cesium hydroxide.Cesium reacts violently with water, phosphorus, sulfur as well as halogens of the periodic table.Cesium has only 1 electron in its outermost orbit and it loses this electron to become stable during a chemical reaction.Cesium is such a reactive metal that is required to be kept under kerosene or a mineral oil.But it is always found as a compound with other elements. Cesium is a highly reactive chemical element and because of this, it is not found in its free state.Chemical properties of IndiumĬhemical properties of indium are mentioned below. Cesium has many isotopes, but out of those isotopes, the isotope 133Cs is the most abundant one (almost 100%).The crystal structure of cesium is FCC (face centered cubic). ![]() The atomic mass of cesium is 132.91 u and its density is 1.88 g/cm 3.The melting point of cesium is 28.5 ☌ and its boiling point is 671 ☌.Cesium is a ductile metal which can be drawn into thin wires.Cesium is a soft metal at room temperature (it is soft like wax).Cesium is a solid metal having a Silvery pale gold appearance.Physical properties of indium are mentioned below. The physical and chemical properties of indium element are mentioned below. Pollucite (which is the ore of cesium) has the largest deposits at Bernic lake in Canada.Cesium was discovered by Gustav Kirchhoff and Robert Bunsen (in 1860).The density of cesium is twice that of the density of water.Cesium is the 50th most abundant element found from the earth’s crust.The amount of cesium present in the earth’s crust is approximately 3 ppm by weight.Cesium was the first element that was discovered with a spectroscope.The name cesium was derived from the Latin word “caesius”, which means sky blue.Interesting facts about indium element are mentioned below. So the last electron of cesium enters the s-subshell or s-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of cesium is 6s 1. How can you determine the blocks-wise position of elements? Gustav Kirchhoff and Robert Bunsen (in 1860) CAS number īefore knowing this reason, first of all I want to ask you a simple question.
