1. Naming Binary Ionic Compounds

2. Review Ionic Compounds:
A compound composed of oppositely charged ions.
Many are used to produce paper
The pulp and paper mill in Thunder Bay

3. Periodic Table and Ion Formation

4. Valence electrons
An electron in the outermost occupied energy level.

6. Naming Binary Ionic Compounds
There are two ways to identify a compound:
Chemical Name
Chemical Formula
IUPAC
International Union of Pure and Applied Chemistry
Binary Ionic Compounds
Compound composed of a metal cation and a non-metal anion

7. Rules for Naming
The first part of the name always identifies the positive ion, which is the metal cation. Thus, this part of the name is the name of the metal.
The second part of the name always identifies the negative ion, which is the non-metal anion. The name of the non-metal ion always ends with the suffix ide.

8. Blue – Metals
Teal – Non-metals
Light Purple - Metalloids

9. Examples Magnesium and Phosphorus Sodium and chlorine
Magnesium phosphide
Sodium and chlorine
Sodium chloride

10. Determining the Chemical Formula
Cross-over method
Identify the metal and non-metal
Write the symbols
Write the charges
Cross over the charges from top to bottom
Remove the charge
Simplify the numbers and remove the 1’s
