Q: Which of the following nuclear equations correctly represents gamma emission?

$^{60}_{27}\text{Co} \rightarrow ^{60}_{27}\text{Co} + ^0_0\gamma$

Q: Which of the following best explains why gamma rays are often emitted alongside alpha or beta particles during radioactive decay?

Gamma emission allows the nucleus to lose excess energy after alpha or beta decay.
