1. Chapter 5
Nomenclature

2. Naming Metal + Non Metal Compounds
Forms a binary ionic compound
Made up of a cation(+ charge) and an anion(- charge)
Two types of compound
Some metals form only one type of cation
Other metals can form two or more cations that have different charges…We use a roman numeral after the cation name to indicate the charge.

3. continued Always name the cation first and the anion last
Then take the name of the cation
Then take the first part of the anion name and add –ide to it

4. Naming Compounds with Polyatomic Ions
First use the name of the cation
Then add the name of the anion

5. Writing Formulas From Names
Some metals have two charges
When a metal has more than one charge, you need to represent that charge in the name
Use a roman numeral( ex II) next to the metal to show the charge
You need to know the name of elements and Polyatomic ions
