Warm up 10-19-15
1. Covalent bonds are between _____ and _____ elements
2. Ionic bonds are between _____ and _____ elements
3. Identify if these compounds are ionic or covalent: FeS, CO2, Cl2 and AlBr3
- Ionic bond has metal elements - Covalent bond has no metal elements
Naming Covalent (Molecular) Compounds
1. Use a prefix to indicate the amount of each element in the compound2. Never use mono– on the first element name. 3. Give the last element an –ide ending.
Naming Ionic Compounds1. Ending element change to –ide. (no prefixes)2. Make sure all the charge cancel each other out3. If there is a transition metal you indicate the charge with a roman numeral after the name of the metal.4. If it is a polyatomic ion, you simply use the name as it is. (no –ide)
