Bromine 76
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. Web6) Krypton-76 absorbs a beta particle to form bromine-76. 7) Aluminum-27 absorbs an alpha particle to form phosphorus-30 and emits a neutron 8) Nitrogen-14 absorbs an alpha particle to form oxygen-17 and emits a proton 9) When neptunium-239 decays, plutonium-239 is formed and a particle is emitted.
