The Rules for Ionic Compounds
Cations, or positive ions, aren't changed.
Anions, or negative ions, have the suffix -ide added to them.
Write the ions for the following names:
Name these ions:
Naming Ionic Compounds
Steps to create names:
Name Cation (+)
Name Anion (-)
Name of K ?

Name of Compound?
Try this one on your own:
Worked by Mr. Angell
If there's a transition metal, you
find the charges!
CuO vs Cu O
Carbon dioxide CO versus carbon monoxide CO
To tell how many atoms of an element there are in a molecule, we use prefixes.
To name a Molecular Compound:
1. The first element is named first, using the elements name.
2. Second element is named as an Anion (suffix "-ide").
3. Prefixes are used to describe the number of atoms.
Exception: "Mono" is not used to name the first element.
What would be the molecular compound name for water?
First, name the hydrogen.
Second, name the oxygen.
We know this charge.
But what about these?
Metals that can have more than one charge need parenthesis.
CuO vs Cu O
Copper (II) Oxide
Copper (I) Oxide
