Answer 1

The statement that best describes the type of radioactive decay shown in the model is:

The model shows alpha decay, which is not a type of nuclear fission.

Alpha decay involves the emission of an alpha particle (which consists of two protons and two neutrons) from the nucleus of an atom, while nuclear fission refers to the splitting of a heavy nucleus into two lighter nuclei, along with the release of energy.
