Chapter 29

1. The energy involved in holding an atomic nucleus together
7. A particle that is transferred between objects and is seen to mediate a force or interaction between those objects
9. A ___ radionuclide undergoing alpha or beta radioactive decay will result in a different daughter product/daughter nuclide.
11. Subatomic particles with a spin of 0, 1, or 2
12. In ___ radiation, radionuclides emit energy. This often accompanies one of the other forms of nuclear radiation.
14. A rarer (when observed in the natural world) form of radioactivity is the spontaneous ___ of atoms with very large nuclei.

2. Emission of particles and rays from unstable atomic nuclei
3. Emitting visible light
4. In ___ radiation, particles consisting of two protons and two neutrons are emitted, usually because the atomic nucleus is too large to be stable.
5. Supergroup of composite particles made up of combinations of elementary fermions and bosons.
6. Subatomic particles with a spin of 1/2
8. The necessary concentration of nuclei for a continuous chain reaction
10. Nuclear radiation is classified as ___ radiation because the energetic particles and rays emitted can strip electrons from atoms as they collide with them.
11. In ___ radiation, particles - either positrons or electrons - are emitted to adjust the ratio of protons and neutrons in an atomic nucleus.
13. A particle with the same mass and spin as another, but opposite charge and magnetic moment
