The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.Ok so I'll take you through some interesting facts and data about Cesium (That most people don't know).
Cesium Overview
Atomic Symbol
Cs (Cesium)
Description
Very soft, light gray, ductile metal.
State at 20 °C
Solid
Sources
Found in pollucite [(Cs4Al4Si9O26).H2O] and as trace in lepidolite.

Uses
Used as a 'getter' to remove air traces in vacuum and cathode-ray tubes. Also used in producing photoelectric devices and atomic clocks. Since it ionizes readily, it is used as an ion rocket motor propellant.
