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

1. First, begin by writing the name of the first element. Carbon - C. 2. Since, CO is a molecular compound (two non-metals joined together), we have to use the appropriate prefix for the second element. 3. Note that the second element, oxygen, has only one atom. This means we have to use the prefix "mono" and change oxygen's ending to oxide. 4. Combine the two names to get $$Carbon Monoxide.$$
