4. the process by which an unstable atomic nucleus loses energy by radiation.
6. the process in which atoms are split creating energy
9. Commonly used reactant in nuclear fusion reactions

1. the process by which an unstable atomic nucleus loses energy by radiation.
2. the product desired in nuclear facilities
3. the most commonly used fuel in nuclear fission reactions
5. each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
6. the process in which atoms are fused creating energy
7. Most known biproduct of fusion reactions
8. Outerspace vessel that harbours nuclear fusion
11. a particle that consists of protons electrons and neutrons
