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 85?
The answer is Astatine (At). However there are a lot of interesting facts about Astatine that people don't know. Let me show you:

Astatine Overview
Atomic Symbol
At (Astatine)
Description
Unstable, radioactive member of the halogen group.
Sources
Does not occur in nature. Similar to iodine. Produced by bombarding bismuth with alpha particles.
