Radium decay type
WebThe particle or ray energy released during decay is called radiation. Uranium is the first in a long chain of radioactive elements that decay until the stable element lead is formed. Important daughter products within the uranium decay chain are radium, radon, and polonium(fig. 2). Radium is the immediate precursor and source of radon. WebRadium decays to form radon. Which equation correctly describes this decay? 226/88Ra -> 222/86Rn + 4/2He Radium decays to form radon. 226/88Ra → 222/86Rn + 4/2He This type of nuclear decay is called alpha decay Gold can undergo transmutation. Which equation could correctly describe this radioactive decay? 185/79Au -> 181/77Ir + 4/2He
