1. Neutrino A lepton with no electric charge. Neutrinos participate only in weak and gravitational interactions and are therefore very difficult to detect.
2. Neutron A baryon with electric charge zero; it has the basic structure of two down quarks and one up quark (held together by gluons).
3. Nuclear reactor A device in which a fission chain reaction can be initiated, maintained, and controlled.
4. Nucleon Proton or neutron, part of atomic nucleus.
5. Nucleonics The science, technology, and application of nuclear energy.
6. Nucleus (NOO-klee-us) In biology, the structure in a cell that contains the chromosomes.
7. Nuclide Any species of atom that exists for a measurable length of time. A nuclide can be distinguished by its atomic weight, atomic number, and energy state.
