Bromine is a chemical element with the symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Anci… WebNov 3, 2015 · Each bromine molecule consists of 2 atoms of bromine .

WebSep 20, 2024 · Fluorine has greater ionization energy than bromine because its valence electrons are more strongly attracted to its positively charged atomic nuclei. This is due to the fact that fluorine atoms only have two energy levels, therefore there is no substantial shielding effect.
