1. REVIEW  Ionic Compounds: (REVIEW: Ions are made up of a ______________ and a __________________.) First name the _____________________ then the ____________________.  Binary Molecular Coupounds: (REVIEW: Molecules are made up of a ______________ and a __________________.)

2. Diatomic molecules  Diatomic molecules :  What are the diatomic molecules?

3. Rules for Naming molecules  Rules are the same as ionic compounds however, now include prefixes Mono is only for second element!!! 2.Prefixes: 1= 6= 2=7= 3=8= 4=9= 5=10= Mono is only for second element!!! http://www.chemistry.ohio-state.edu/~woodward/ch121/ch2_naming.htm

4. Examples N 2 O 3 = NF 3 = PCl 5 = P 2 O 5 = O 2 = CO 2 = http://www.chem4kids.com/files/atom_naming.html

5. Flow Chart  If you are a visual person, this might make naming compounds easier: http://dbhs.wvusd.k12.ca.us/webdocs/Nom enclature/HO6-Flowchart-Naming.pdf
