E.3.7—Decay nuclear changes question 1

[Maximum number: 1]

Rhodium-106 (45106Rh)\left({ }_{45}^{106} \mathrm{Rh}\right) decays into palladium-106 (46106Pd)\left({ }_{46}^{106} \mathrm{Pd}\right) by beta minus (β−)\left(\beta^{-}\right)decay. The diagram shows some of the nuclear energy levels of rhodium-106 and palladium-106. The arrow represents the β−\beta^{-}decay.
