1. I can name binary molecular compounds given the formula. I can determine the formula of a binary molecular compound given the name. Learning Targets

2. Binary molecular compounds are named using Greek prefixes. Here are the prefixes you will need to know: Naming Binary Molecular Compounds

3. The first element in the formula is named first, and the full element name is used. The second element is named by dropping the ending and adding -ide. Prefixes are used to denote the number of atoms present. The prefix mono- is never used for naming the first element. For example, CO is called carbon monoxide, not monocarbon monoxide. If the element name begins with a vowel, the vowel is typically dropped from the prefix name. For example CO4 would be called carbon tetroxide, not carbon tetraoxide.

4. The prefix is translated and written as a subscript to the right of the element symbol. The elements are written in the formula in the order they appear in the name. For example, carbon tetroxide would be written as CO4. Formulas for Binary Molecular Compounds
