Developed the concept of radioactive half-life, discovered the element Radon and differentiated between alpha and beta radiation, E. Rutherford was famous for the first artificially induced nuclear reaction. By bombarding the Nitrogen nuclei with alpha particles, he discovered an emission of a subatomic particle, which is now known as the proton. Long after his death, the radioactive chemical element # 104, Rutherfordium was named in his honor.
