Under certain circumstances, a nucleus can decay by emitting a particle more massive than an alpha -particle. Consider the following decay processes: ._(88)Ra^(223)to._(82)Pb^(209)+._(6)C^(14) , ._(88)Ra^(223)to._(86)Rn^(219)+._(2)He^(4) (a) Calculate the Q-values for these decays and determine that both are energetically allowed.
