splitting the nucleus of an atom into parts
submit answer

Explanation:

Nuclear fission is a process in nuclear physics. It involves splitting the nucleus of an atom (such as a heavy - atom like U - 235) into smaller parts. Bonding other atoms to the nucleus of U - 235 is not fission. The bonds that hold the nucleus of the atom together are related to nuclear forces (like the strong nuclear force), not fission.

Answer:

Splitting the nucleus of an atom into parts.
