| DRAFT DEFINITION |
| Radical ion |
|---|
| An ion, either a cation or anion, containing unpaired electrons in its ground state. The unpaired electron is denoted by a superscript dot alongside the superscript symbol for charge, such as for the molecular ion of a molecule M, that is, M+?????????????????????. Radical ions with more than one charge and/or more than one unpaired electron are denoted such as M(2+)(2?????????????????????).Unless the positions of the unpaired electron and charge can be associated with specific atoms, superscript charge designation should be placed before the superscript dot designation. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
| This is an unofficial draft definition presented for information and comment. |
