Naming Inorganic Compounds
Positive ions (cations)
Cations formed from metal atoms have the same name as the metal.
Na+ sodium ion Zn2+ zinc ion
Naming Inorganic Compounds
Positive ions (cations)
If the metal can form ions with more than one charge, the charge is in ( ).
Co+ cobalt() Co2+ cobalt()
Naming Inorganic Compounds
metal names
Lower charge gets the ous Higher charge gets the ic
Fe2+ = Fe(II) = Ferrous FeCl2 = ferrous chlorideFe3+ = Fe(III) = Ferric FeCl3 = ferric chloride
Cu+ = Cu(I) = cuprous CuBr = cuprous bromide
Cu2+ = Cu(II) = cupric CuBr2 = cupric bromide
Hg+ = Hg(I) = Mercurous HgI = mercurous iodideHg2+ = Hg(II) = Mercuric HgI2 = mercuric iodide
Naming Inorganic Compounds
Positive ions (cations)
Follow the poly atomic ion list for others
Naming Inorganic Compounds
Negative ions (anions)
Monotomic anions – drop the ending of the name and add –ide.
H- hydride O2- oxide Br- bromide
Follow the polyatomic ion list for others.
Naming Inorganic Compounds
Ionic compounds
Name the cation followed by the anion
CaCl2 calcium chloride
Al2O3 aluminum oxide
Naming Inorganic Compounds
Binary molecular compounds (covalent compounds)
• The name of the element farthest to the left in the table is written first.
• If in the same group, the lower one is named first
• The second element is given the ide ending
• Greek prefixes are used to indicate the number of each atom.
Standard prefixes
1 mono 6 hexa
2 Di 7 hepta
3 tri 8 octa
4 tetra 9 nona
5 penta 10 deca
Naming Inorganic Compounds
Naming Acids
If the acid has no oxygen then simply add hydro as prefix and ic acid as
suffix
Naming Inorganic Compounds
Naming Acids
If the acid contains oxygen
use ic acid if the anion ends in ate
and
use ous acid if the anion ends in ite.
Naming Inorganic Compounds
Naming Acids
If the acid contains oxygen
If the acid has one less O than the ite ion then uses hypo….ous acid
If it has one more O than the ate ion then use per….ic acid.

Name the first atom followd by the second with the ide ending.
Include the number of each
type of atom
The compound contains a transition
No transition metals present
Name first followed by the second with the
ide ending.Include the charge on the metal in ( )
or use ic, ous designation
Name the first followed by the second with the
ide ending
If a polyatomic ion is present
simply use the name of the
polyatomic ion
Contains Oxygen
No Oxygen present
Add hydro as prefix and ic acid
as suffix

One less O than the ite - hypo...ous acidOne more O than the ate - per...ic acid
