Atoms, Molecules, and Ions
Cation named first.
If atom 1 makes only one cation:
Strontium chloride SrCl2
If atom 1 makes several cations:
Iron(III) chloride FeCl3
Less electronegative element named first
Most electronegative gets “anionic” –ide
Greek prefixes show proportions:
Dichlorine heptoxide Cl2O7
Mono prefix is never used for first atom.Naming Compounds
