1. Molecular Compounds

2.  Held together by covalent bonds  Elements involved are nonmetals  Binary Compound: two nonmetals  Example: H 2 O Molecular Compounds

3.  Nonmetals can combine in different ways  Use prefixes to distinguish between the combinations Example: CO and CO2  Prefixes indicate how many atoms of an element are present in each molecule of the compound  CO2 = Carbon dioxide Naming Binary Compounds

4.  1. Write the names in the order of the formula  2. Use prefixed to indicate the number of each kind of atom  If the first element has just one atom, do not use a prefix  3. End the name of the second element with “ide” Steps to Naming Binary Molecules
