Atomic Mass Cs (& Secrets: Uses, Sources and more...) 2022

As anyone would guess, every atom has mass, an important physical property, even Cesium. But how do we know how much does a Cs atom weight?

First of all, if we know the atom symbol, let's say Cs, we can open any periodic table and search for Cesium.

In the case of Cesium the answer is 132,90543. However there is a lot of funny facts about Cesium that most people don't know. Shall we have a look?
