Which anions have the largest and smallest radii? Thank you!!

  • Chemistry URGENT!! -

    The smallest anion probably is H^-. I'm not sure you can say what the largest anion (or cation) is since complex ions can carry a - or + charge and these can get large. It would be complicated to even try to calculate the diameter of those things. For example Fe(CN)63- or UO22+
