Radium E is the seventh and last stage of radium disintegration before it turns into polonium. Its atomic weight is 210. Atomic weight of bismuth is 209. Dr. John Jacob Livingood figured that if he hurled billions of particles of atomic weight i at bismuth, some of them might plow into the nucleus and stick, turning the bismuth into Radium E. Actually, the best particles for his purpose were deuterons whose atomic weight is 2. When the deuterons got close to the bismuth nucleus, they broke into protons and neutrons. The protons recoiled. But the neutrons, of atomic weight...
...Livingood identified the created element by the fact that it began shooting out fast electrons which dwindled by half in about five days. This is exactly the behavior of Radium...
