1. Naming compounds review

2. Ionic bonds Ionic bonds are named just by saying the metal first Ionic bonds are named just by saying the metal first Followed by the non- metal ending in IDE Followed by the non- metal ending in IDE NaCl sodium chlorIDE NaCl sodium chlorIDE The only time you have to add a number is with transition metals The only time you have to add a number is with transition metals

3. Ionic Bonds CuCl 2 for example is Copper II chlorIDE In this case the number represents the charge on the atom because there is more than one So if you have to name a compound that has a transition metal in it, be sure to include its valence

4. Ionic bonds Sometimes we have poly atomic ions attached like Copper II SulfATE Sometimes we have poly atomic ions attached like Copper II SulfATE Here you have to remember to look at the back of your periodic table Here you have to remember to look at the back of your periodic table

5. Ionic Bonds In order to figure out how to write the formula of ionic bonds you need to know the charge In order to figure out how to write the formula of ionic bonds you need to know the charge

6. dinitrogen tetraoxide dinitrogen tetraoxide N O 2 4 I’m molecular 2. Write number of atoms 1. Write symbols of elements Final Formula Molecular bonds These are way easier because we use the prefixes and can write the formula or name easily by knowing the prefixes These are way easier because we use the prefixes and can write the formula or name easily by knowing the prefixes

7. Prefix it! mono1 hepta7 mono1 hepta7 di2 octa8 di2 octa8 tri3 nona9 tri3 nona9 tetra4deca10 tetra4deca10 penta5 undeca11 penta5 undeca11 hexa6dodeca12 hexa6dodeca12 Remember this only applies to TWO NON- Metals Remember this only applies to TWO NON- Metals
