Is astatine a cation or anion
WebUsually how it works is that iron (Fe) will be paired with an anion which has a constant negative charge. This will give the ionic compound an overall charge which both the iron cation and paired anion have to have their charges sum up to. So if you're given FeO and you have to name it we know a few things. http://www.chemistryexplained.com/elements/A-C/Astatine.html
