Binary-type nomenclature

Although it is possible to develop a name based simply on an empirical formula (a reasonable proposal might be calcium sulfur tetraoxygen for CaS04), this is never done. Binary nomenclature is principally inoiganic, and has no real simple organic counterpart. 

This provides names for compounds for which little or no structural information is available. However, a minimum of structural information is known or assumed. In particular, using the assumed or established division of constituents into positive and negative parts already employed above in establishing formulae, we divide the constituents into the same two classes, hence the term binary nomenclature . 

The name is derived by combining the names of the electropositive constituent(s) with those of the electronegative constituent(s), suitably modified by any necessary 

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. 

If there is more than one electropositive constituent, the names should be spaced and cited in alphabetical order of the initial letters, or of the second letters if the first letters are the same. Multiplicative prefixes are ignored for purposes of ordering.

Binary type nomenclature. In this system, the composition of a substance is specified by the juxtaposiliun of element group names, modified or unmodified, together with appropriate numerical prefixes, if considered necessary,...
