Bromine (Br2тАЛ) is the only non-metal that exists in a liquid state at room temperature and standard atmospheric pressure. It is a deep red-brown volatile halogen liquid.
Think of the halogens as a ladder of states at room temperature: Fluorine and Chlorine are light gases at the top, Bromine sits in the middle as a heavy liquid, and Iodine is a solid at the bottom.
B for Bromine is a Brisk, Brown, Boiling liquid non-metal.
Br2тАЛ тАФ Molecular formula of Bromine
Bromine is located in Group 17 (halogens) of the periodic table. While fluorine and chlorine are gases and iodine and astatine are solids at room temperature, bromine has sufficient intermolecular van der Waals forces to remain a liquid, yet low enough vapor pressure to readily form a red-brown vapor.
Bromine is a heavy, reddish-brown volatile liquid at room temperature (25┬░C).
Mercury (Hg) is the only liquid metal at room temperature.
Among halogens, fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.
Used in flame retardants
Used in pharmaceuticals and water purification
Atomic number of Bromine is 35.
Chlorine is a gas, Fluorine is a gas, and Sulphur is a solid.
B is correct тАФ Bromine is the only non-metal that exists as a liquid at room temperature.
Always remember the distinction: Bromine is the only liquid non-metal, whereas Mercury is the only liquid metal.
