Group Number of Cesium (& Uses, Sources ... 2022

As anyone would guess, every atom has a group name assigned, even Cesium. But how do we know what is the group name for an atom of Cs?

First of all, if we know the atom symbol (or name), let's say Cs, we can open any periodic table and search for Cesium. If the periodic table is complete just scroll up and read the number on the top (from 1 to 18).

In the case of Cesium the group number is 1. However there is a lot of funny facts about Cesium that most people don't know. Shall we have a look?

Solid

Discovery

Discovered By: Gustov Kirchoff, Robert Bunsen
Year: 1860

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.
