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.
