Naming of Radical and Ionic Species

In principle, all radicals and ions can nowadays be named in a uniform and totally systematic manner on the basis of the operational suffixes (and prefixes derived therefrom) compiled in Table 11. Obviously, standardization of the nomenclature for such derived species can be fully congruous only if the names of the underlying parent structures themselves are generated in a thoroughly systematic way, e.g. oxidane, dioxidane, azane, diazane, etc. Hence, in the subsequent sections fully systematic names are always given as well as the conventional trivial/traditional designations. 

Addition Subtraction yla -ylo -ium -ide -iumyl -idyb -uide -ylium -uidyl -yliumyl 

Subtraction of two and three H-atoms is expressed by -ylidene, -ylidyne, with the exception of methylene ( CH2), silylene ( SiH2) etc., and aminylene For cations comprising core elements of groups 15-17 the traditional -onium suffixes and -onio- prefixes are still prefered. 

For anions of acids, alcohols, sulfides etc. the traditional suffixes -ate, -oxide, -sulfide and prefixes -ato-, -ido- are still retained.
