1. Unit 4: Inorganic Nomenclature
October 4th

2. Metals and Non-Metals
Your new
best friend!

3. Ions
atom or molecule that has an electrical charge (due to the gaining or losing of an electron) (49)
Give me some examples!

4. Ionic compounds
positive ions (ex) Na+) and negative (ex) Cl-) form ionic compounds
Remember: ions are charged, but compound are neutral (no charge)
KEYWORDS
anion: ion with –ve charge
cation: ion with a +ve charge

5. ion charges

6. keywords p68
monatomic
diatomic
triatomic
polyatomic

7. Take a look at ions P3- What is the element?
Metal or non-metal (or transition/metalloid)?
Monatomic, diatomic?
What is the charge?

8. Naming Monatomic Metal Ions
a. Metal with one possible charge – name stays the same
Ex. Sodium (Na)  Sodium ion (Na+)
b. Metal with more than one possible charge – name stays the same, but number is included.
Ex. Fe3+  Iron (III) ion or Fe2+ Iron (II) ion

10. Naming Polyatomic Ions p69
These will be given to you in the data table.

11. Naming Ionic Compounds p70
Ionic compounds = positive ion(s) + negative ion (s) forming an ionic bond
