Group Number Cesium (Cs) (& Color, Uses ... 2022

All atoms have a group name assigned, even Cesium. Ok but how do we know what is the group name for an atom of Cs?

If we know the symbol, let's say Cs, we may then open any periodic table and search for Cesium. Any decent periodic table should have the group numbers when you scroll up starting from the element you found.

In the case of Cesium the group number is 1. There is a lot of cool stuff about Cesium that people simply don't know. Why not stick around for a bit?
