WebAn example of alpha decay is uranium-238: 23892U → 23490X + 42He. The atomic number has dropped from 92 to 90. The chemical element with Z = 90 is thorium. Hence, Uranium-238 has decayed to Thorium-234 by the emission of an α particle, written 23892U → 23490Th + 42He. Subsequently, 23490Th decays by β emission with a half-life of 24 … WebUranium-234 (234 U or U-234) is an isotope of uranium. Thus the rate of 234 U to 238 U in a natural sample is equivalent to the rate of their half lives to one another.
