Answer 1

The correct description of nuclear fission is:

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

This process typically involves a heavy nucleus absorbing a neutron, becoming unstable, and then splitting into two or more smaller nuclei, along with the release of energy and additional neutrons.
