Word Origin and History for bromine
nonmetallic element, 1827, from French brome, from Greek bromos "stench." With chemical suffix -ine (2). The evil-smelling dark red liquid was discovered by French chemist Antoine Jérôme Balard (1802-1876), who initially called it muride.
- A volatile nonmetallic liquid element having a highly irritating vapor and used in disinfecting water and in various pharmaceuticals. Atomic number 35.
- A reddish-brown volatile element of the halogen group found in compounds occurring in ocean water. The pure form is a nonmetallic liquid that gives off a highly irritating vapor. It is used to make dyes, sedatives, and photographic film. Atomic weight 79.904; atomic number 35; melting point 7.2°C; boiling point 58.78°C; specific gravity 3.12; valence 1, 3, 5, 7.
