Index of Common and Uncommon Ions

I compiled the bulk of this list a few years ago, because I was intered in knowing how many simple ions there were. I generally made this list using the internet as reference, but unfortuntaely the internet is a pretty poor reference for Chemistry, and I don't study it myself. Thus, it's likely that there are errors in this table. If you find any (or have ions you want to add), please let me know.
