9. Technetium-99 is prepared from Mo. Molybdenum-98 combines with a neutron to give molybdenum-99, an unstable isotope that emits a ß particle to yield an excited form of technetium-99, represented as "Tc. This excited nucleus relaxes to the ground state, represented as ⁹9Tc, by emitting a y ray. The ground state of Tc then emits a ß particle. Write the equations for each of these nuclear reactions.
