Nuclear Energy

2. The most powerful type of radiation wave; can pass through thick materials.
4. Thick protective walls that block radiation from escaping.
5. The neutral (no charge) particle found inside the nucleus.
7. The process of splitting a heavy nucleus into two smaller pieces.
9. A type of plant that uses a nuclear reaction to create energy.
10. The ability to do work or cause change.
14. The property of matter that causes it to experience a force in an electric field (positive or negative).
15. A type of radiation that is a fast-moving electron.
16. Energy of motion, like the energy of the turbine spinning.
19. A machine with fan blades that spins when hit by steam or wind.
20. The weakest type of radiation particle; can be blocked by paper.
21. Anything that has mass and takes up space.
22. Atoms of the same element that have a different number of neutrons.
23. Relating to the nucleus of an atom.
26. The device that converts the motion of the turbine into electrical energy.
28. The smallest unit of matter; the basic building block of all elements.
29. The process of combining two light nuclei to form one heavier nucleus.

1. The time it takes for half of a radioactive sample to break down.
3. The positively charged particle found inside the nucleus.
6. Pieces inserted to absorb extra neutrons and slow the reaction.
8. An atom that has gained or lost an electron, giving it a charge.
9. Stored energy, like the energy stored in the nucleus of the atom.
11. An unstable material that gives off particles and energy.
12. Energy given off in the form of particles or waves.
13. The unused and highly contaminated materials left over from the process.
17. The flow of energy from power plants to our homes and devices.
18. The tiny, dense, positively charged center of an atom.
24. The container used to control a nuclear chain reaction.
25. The process by which an unstable nucleus spontaneously breaks down.
27. The negatively charged particle that orbits the nucleus.
