Nuclear Reactions

A rare decay mode has been observed in which \({ }^{222} \mathrm{Ra}\) emits a \({ }^{14} \mathrm{C}\) nucleus. (a) The decay equation is \({ }^{222} \mathrm{Ra} \rightarrow{ }^{A} \mathrm{X}+{ }^{14} \mathrm{C}\).  Identify the nuclide \({ }^{A} \mathbf{X}\). (b) Find the energy emitted in the decay. The mass of \({ }^{222} \mathrm{Ra}\) is 222.015353 u.
