WebBromine was discovered, at almost the same time in 1826, by two men, German chemist Carl Lowig (1803-90) and French chemist Antoine-Jerome Balard (1802-76). While Balard announced his discovery first, Lowig had simply not completed his studies of the element when Balard made his announcement. WebBromine is the 35th element of the periodic table so its atomic number is 35. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a bromine atom has thirty-five protons and thirty-five electrons.

WebBromine-76 decays by electron capture and positron emission with 16 hour half-life. Several energy levels of selenium-76 appear in this process. Measurements of the radiations emitted in the decay of bromine-76 have been reported.
