Electropositive constituent unmodified

When forming a complete name one leaves the name of the electropositive constituent unmodified, except when it is necessary to indicate the valency (see below) and the same applies to the name of that one of a pair of non-metals which is cited first in the list above. The name of the electronegative constituent, or of the non-metal named second, is modified to end in -ide. Normally this modification is carried out by stripping the name of the element back to the penultimate consonant and then adding ide , as in carbon, carb, carbide or chlorine, chlor, chloride but the following exceptions shoidd be noted ... 

The name of the electropositive constituent is simply the unmodified element name, the name of a polyatomic cation or an accepted group name, as appropriate. 

Electropositive condiments. The name of a monoatomic electropositive constituent is simply the unmodified element name. A polyatomic constituent assumes the usual cation name, but certain well established radical names (particularly for oxygen-containing species such as nitrosyl and phosphoryl) are still allowed for specific cases... 

Where an element symbol occurs in the first column, the unmodified element name is listed in the second and diird columns. The unmodified name is generally used when the element appears as an electropositive constituent in the construction of a stoichiometric name (Sections IR-5.2 and IR-5.4). Names of homoatomic cations consisting of the element are also constructed using the element name, adding multiplicative prefixes and charge numbers as applicable (Sections IR-5.3.2.1 to IR-5.3.2.3). The sections mentioned refer to parts of Nomenclature of Inorganic Chemistry. lUPAC Recommendations 2005, see above. 

Binary compounds are named by citing the name of the electropositive constituent first, unmodified, followed by the name of the electronegative constituent, modified to end in -ide. For this purpose, an agreed series is used, based on the electrochemical series given above.
