Bromine and Bromine Molecule

**Symbol:** Br **Atomic number:** 35 **International name:** Bromine **General formula:** Br₂ **Relative Atomic Weight:** 79.904 **Description:** Bromine is a toxic, reddish-brown liquid that is highly volatile and evaporates rapidly at room temperature. Its vapors are extremely hazardous. Like other halogens, bromine forms diatomic molecules (Br₂) with a single bond between the two atoms, and it is classified as a typical non-metal. **Applications:** Bromine is used as a raw material in the chemical industry and in the production of pharmaceuticals (e.g., cough suppressant drops) and in the production of halogen light bulbs. **Occurrence:** Bromine is relatively scarce on Earth and found only in the form of compounds. The largest natural source of bromine is seawater, where it occurs in dissolved form.
