## Chemistry: A Molecular Approach (3rd Edition)

Copper (I) Iodate - $CuIO_{3}$
1. To begin, write the name of the first element with its charge. (We are told that copper has a charge of 1). Cu$^{+}$ 2. Then write the name of the second element with its charge. (Note - Iodate is a poly-atomic ion so, you have to remember its charge.) IO$_{3}^{-}$ 3. Cross down the charges on both of the elements (+1 and -1) to get: $$CuIO_{3}$$
