Examine the nuclear reaction: Superscript 1 subscript 1 H plus superscript 1 subscript 0 n right arrow superscript 2 subscript 1 H.. Why is this classified as a nuclear reaction rather than a chemical reaction?

Because the reaction changes the nucleus itself: a free neutron is captured by a hydrogen nucleus (a proton) to form a deuteron (2H). Chemical reactions involve rearrangement of electrons between unchanged nuclei; they do not change nucleon number or convert one isotope into another.
Key points:
- The process alters nucleon composition (A changes from 1 to 2), so it is a nuclear transmutation (neutron capture), not an electron-driven chemical process.
- It is governed by the strong nuclear force and typically involves MeV-scale energy changes (often emitting a gamma), whereas chemical reactions are governed by electromagnetic interactions of electrons and involve eV-scale energies.
- Chemical reactions cannot create or bind neutrons to nuclei; only nuclear reactions can.
