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….

Now practice:

 

Ca2+ + O2- → CaO

 

3Na+ + N3- → Na3N

 

3Ca2+ + 2N3- → Ca3N2

 

Now practice:

 

Ca2+ + O2- → CaO

  Calcium Oxide

Na+ + N3- → Na3N

  Sodium Nitride

Ca2+ + N3- → Ca3N2

Calcium Nirtide

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
