Atomic Symbol 18 (& 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 18?

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