Bromine (Br). Diagram of the nuclear composition, electron configuration, and valence orbitals of an atom of bromine-80 (atomic number: 35), an isotope of this element. The nucleus consists of 35 protons (blue) and 45 neutrons (red). The stability of an element's outer (valence) electrons determines its chemical and physical properties. Bromine is a halogen in group 17, period 4, and the p-block of the periodic table. In elemental form it is a red-brown, corrosive and toxic liquid (Br2) that boils at 59 degrees Celsius. Its main use is in fire retardant compounds. | |
