Explanation:

1. Isotope: Atoms of the same element with different neutrons (D).
2. Chain reaction: Fission neutrons split nuclei, more neutrons (C).
3. Strong nuclear force: Binds protons/neutrons, strongest (N).
4. Weak nuclear force: Causes beta decay, 3rd strongest (K).
5. Electromagnetic force: Charged object force, 2nd strongest (L).
6. Transmutation: Unstable nuclei decay to stable (M).
7. Alpha decay: Emits two protons/neutrons (A).
8. Beta decay: Neutron to proton/electron (B).
9. Gamma decay: Emits high - energy EM radiation (G).
10. Binding energy: Energy to pull nucleus apart (I).
11. Radiation: Flow of EM from radioactive decay (R).
12. Daughter nucleus: Stable from parent decay (D).
13. Radioactive: Atoms with unstable nuclei eject particles (E).
14. Half - life: Time for half parent to decay (H).
15. Fission: Big nuclei decay to smaller (F).
16. Fusion: Smaller nuclei to larger (J).
17. Parent nucleus: Unstable, decays to daughter (P).
18. Nuclei: More than one nucleus (Q).

Answer:

1. D. Atoms of the same element that have different numbers of neutrons (giving them different masses).
2. C. During a fission reaction when free neutrons split nuclei, more neutrons are released and they split more nuclei, and so on.
3. N. Nuclear force responsible for binding the protons and neutrons. Strongest nuclear force.
4. K. Force in the nucleus responsible for beta decay. \(3^{rd}\) strongest nuclear force.
5. L. Force of attraction or repulsion of charged objects. \(2^{nd}\) strongest nuclear force.
6. M. a.k.a. radioactive decay. Unstable nuclei break down to a stable product.
7. A. Type of radioactive decay where two protons and two neutrons are emitted from a nucleus.
8. B. Type of radioactive decay where a neutron converts to a proton and an electron.
9. G. Type of radioactive decay that lowers the energy of the nucleus and emits high energy electromagnetic energy.
10. I. The energy needed to pull a nucleus apart (or the energy holding a nucleus together).
11. R. The flow of electromagnetic radiation that is a result of radioactive decay.
12. D. Stable nucleus that is the result of radioactive decay of a parent nucleus.
13. E. Atoms having unstable nuclei will eject protons, neutrons or electromagnetic radiation.
14. H. Time it takes for half of parent nuclei to decay to daughter nuclei.
