Questions and Answers

What is radioactive decay?

Radioactive decay is the spontaneous breakup of an unstable nucleus.

How does the emission of alpha or beta particles affect the identity of the nucleus?

The emission of either alpha or beta particles changes the identity of the nucleus due to a loss in nucleon charge.

What happens when a gamma ray is emitted during radioactive decay?

The emission of a gamma ray simply reduces the energy level of the nucleus.
