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

The model shows alpha decay, which is a type of nuclear fission.

Answer 1

The correct statement is:

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

Alpha decay involves the emission of an alpha particle (consisting of 2 protons and 2 neutrons) from the nucleus of an atom, while nuclear fission refers to the splitting of a heavy nucleus into smaller nuclei.
