Answer 1

The correct response that describes nuclear fission is:

starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.

Nuclear fission is the process where a heavy nucleus splits into smaller nuclei, along with the release of energy and neutrons, typically initiated by the absorption of a neutron.
