RESULTS AND DISCUSSION … WebbUranium 238 is the most abundant isotope of Uranium. The long sequence of decays in the Uranium Radium series starts with U-238 and eventually ends up as a stable isotope of lead. But along the way, one of the elements produced is Radon, which is the only one in the sequence that is potential dangerous because it doesn't combine with other atoms in its …
WebbAll uranium atoms contain 92 protons (Z = 92) and various numbers of neutrons (N = 135 to 148) within the atom's nucleus. There are no stable isotopes of uranium; all are radioactive. The half-lives of uranium isotopes range from less than 2 minutes (227U) to billions of years (^U).
