Bromine is a highly reactive element and forms compounds with many other elements. Some of the elements that bromine mixes well with include:

- Metals: Bromine reacts with metals to form bromides. For example, bromine reacts with sodium to form sodium bromide (NaBr).

- Non-metals: Bromine reacts with non-metals to form covalent compounds. For example, bromine reacts with hydrogen to form hydrogen bromide (HBr).

- Halogens: Bromine reacts with other halogens to form interhalogen compounds. For example, bromine reacts with chlorine to form bromine chloride (BrCl).

- Organic compounds: Bromine reacts with organic compounds to form a variety of products, including bromoalkanes, bromoalkenes, and bromoarenes.
