Chapter 21, Problem 16E

Technetium-99 is prepared from ⁹⁸Mo. Molybdenum-SS combines with a neutron to give molybdenum-99, an unstable isotope that emits a $\text{β}$ particle to yield an excited form of technetium-99, represented as ⁹⁹Tc*. This excited nucleus relaxes to the ground state, represented as 99Tc, by emitting a $\text{γ}$ ray. The ground state of ⁹⁹Tc then emits a $\text{β}$ particle. Write the equations for each of these nuclear reactions.
