Radical ion

An ion, either a cation or anion, containing an unpaired electron. The unpaired electron is denoted by a superscript dot alongside the superscript symbol for charge, such as for SF₆ ^{-?????????????????????}. Radical ions with more than one charge and/or more than one unpaired electron these are denoted as X^{(2+) (2?????????????????????)} or X^{(2?????????????????????) (2+)}.Unless the positions of unpaired spin and charge can be associated with specific atoms, superscript dot and charge designations should be placed in the order ^{+1?????????????????????} or ^{-?????????????????????} e.g. C₃H₆^{+1?????????????????????}.
