Atomic Symbol 55 (& Cool facts: Uses, Sources, Color and more...) 2022

Every atom has a symbol and some are easy to figure out. Especially if you already know its name.

But what do you do when you only know its atomic number? Like... what is the atom symbol whose atomic number is 55?

The answer is Cesium (Cs). However there are a lot of interesting facts about Cesium that people don't know. Let me show you:
