Edited This post to correct the atomic mass of polonium included in the text, I switched periodic tables 4 times during the creation of this, and the mass reflected the reported value on a different table. They vary in reporting 209 vs 210.

Second Edit: Fixed a typo and became an. Missed a period for a full ellipsis, which was also fixed.
Third Edit: Fixed Spelling, Missed a letter (x) in Sulfur Hexafluoride.
Final Edit: changed it to I in the legend section at the top.
