Chemistry: A Molecular Approach (3rd Edition)

BrF$_{5}$ - Bromine Pentafluoride
1. First, begin by writing the name of the first element. Br -Bromine. 2. Since, BrF$_{5}$ 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 , fluorine, has five atoms. This means we have to use the prefix "penta" and change fluorine's ending to fluoride 4. Combine the two names to get: $$Bromine Pentafluoride$$
