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.
