Naming Binary Ionic Compounds with Fixed-Charge Cations
Captions available
The idea
A binary ionic compound with a fixed-charge cation is named by stating the metal's name, then the nonmetal's name changed to end in -ide.
In practice
Sodium and chlorine combine as NaCl, named sodium chloride: sodium unchanged, chlorine's ending replaced by -ide.
Where people slip
This method only works when the metal's charge is fixed and unambiguous — variable-charge metals need an added charge marker, covered next.
