NAMING IONIC COMPOUNDSMonoatomic ions (ions made up of only one
atom) are named by changing the end of the element name to -ide
for example:
bromine (Br) becomes bromide (Br -)
tellurium (Te) becomes telluride (Te-2)
sulfur (S) becomes sulfide (S-2)
When naming an ionic compound, you first give the name of the cation element, then the anion with the -ide ending.
For example;
NaCl is sodium chloride
Lets name the compounds from the first practice slide….

Polyatomic Ions
Polyatomic ions are ions made up of more than one atom
There are 15 polyatomic ions (ions made up of more than one atom)
I will give you the chart on page 178 of the text for the test, so when you see the formula, you need to be able to tell me the name.
Here are some of them….
OH- hydroxide
SO4 2- sulfate
SO32- sulfite
O22- peroxide
NO2- nitrite
NO3- nitrate
MnO4- permanganate
The same rules apply when dealing with polyatomic ions.(remember, the charge associated with the polyatomic ion applies to the entire ion) K+ + CN- → KCN2Na+ + O2
2- → Na2O2
Mg2+ + 2NO2- → Mg(NO2)2
(by putting parenthesis around the Nitrite portion of the compound, the following subscript tells us that there are 2 nitrite ions for every one Magnesium ion in this compound)

Naming Compounds that have TRANSITION METALS
because transition metals can have more than one charge, you must include the charge of the metal, in the form of a Roman Numeral, in the name. For example…
Fe 2+ + 2OH- Fe(OH)2
The product is named Iron (II) Hydroxide
Fe3+ + 3OH- Fe(OH)3
This product would be named
Iron (III) Hydroxide
