For example, uranium-238 (which decays in a series of steps into lead-206) can be used for establishing the age of rocks (and the approximate age of the oldest rocks on earth). Since U-238 has a half-life of 4.5 billion years, it takes that amount of time for half of the original U-238 to decay into Pb-206.

Draw an arrow that connects each decay product to the one that it will decay into. This will take a little thought (make sure that the nuclear equations for alpha and beta decay would be balanced). Next to each arrow, label if the isotope undergoes alpha-decay or beta-decay to get to the next isotope in the decay series.

Decay Series. The decay of a radioactive nucleus is a move toward becoming stable. Often, a radioactive nucleus cannot reach a stable state through a single decay. In such cases, a series of decays will occur until a stable nucleus is formed. The decay of \(\ce{U}\)-238 is an example of this.

Another series headed by 235 U contributes very little. Members of the two important series are listed in Table I.Many of the radionuclides in these series decay by emission of alpha particles with energies from 4 to 6 MeV.
