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.
