Fission differs from a simple chemical reaction in several significant ways:
1. **Atomic Structure**: In fission, the nucleus of a heavy atom (usually a radioactive isotope, such as uranium-235 or plutonium-239) splits into two or more smaller nuclei along with the release of energy. This process involves changes to the atomic nucleus. In contrast, chemical reactions involve the rearrangement of electrons in the outer shells of atoms without altering the nuclei themselves.
2. **Energy Release**: Fission reactions release significantly more energy compared to typical chemical reactions. The energy released during fission is a result of the strong nuclear forces that hold the nucleus together, whereas chemical reactions are much weaker and involve potential energy changes related to electron bonding.
3. **Control of Reaction**: Fission reactions can become uncontrollable, especially in a nuclear chain reaction where the products of fission can induce further fission. This can lead to an exponential increase in energy release, which is a concern in nuclear reactors and weapons. On the other hand, chemical reactions usually can be controlled more easily through reaction conditions like temperature, pressure, and concentration.
4. **Types of Atoms Involved**: Fission typically occurs in heavy, unstable (radioactive) isotopes, while chemical reactions generally involve stable atoms.
In summary, fission is a nuclear reaction involving the splitting of atomic nuclei, resulting in a much larger energy release compared to chemical reactions, which involve electron transfers or sharing between atoms without altering their nuclei.

The correct answer that succinctly captures a key difference between fission and simple chemical reactions is:
**Atoms are split into smaller pieces during fission.**
This statement accurately identifies that fission involves the splitting of atomic nuclei, which is a fundamental distinction from typical chemical reactions that involve the rearrangement of electrons without changing the nuclei.
Although other options provided address some aspects of fission and chemical reactions, this statement most clearly highlights the difference in the process occurring at the atomic level.
