Physical Properties
Bromine does exist as a diatomic molecule, Br2. It is a dense, mobile, slightly transparent reddish-brown liquid, that evaporates easily at standard temperature and pressures to give an orange vapor that has a strongly disagreeable odor resembling that of chlorine. It is one of the only two elements on the periodic table that are known to be liquids at room temperature. At a pressure of 55 GPA bromine converts to a metal. At 75 GPA it converts to a face centered orthorhombic structure. At 100 GPA it converts to a body centered orthohombic monotonic form.
Chemical Properties
Being less reactive than Chlorine but more reactive than Iodine, Bromine reacts vigorously with metals, especially in the presence of water, to give bromine salts. It is also reactive toward most organic compounds, especially upon illumination, conditions that favor that dissociation of the diatomic molecule into Bromine radicals: Br2 > 2Br.
It bonds easily with many elements and has a strong bleaching action.
Bromine is slightly soluble in water, but it is highly soluble in organic solvents such as carbon disulfide, carbon tetra-chloride, aliphatic alcohols, and acetic acid.
Elements with similar properties as Bromine include: Fluorine, Chlorine, Iodine, and Astatine.
