- 3. Particle: A fast-moving electron emitted during the radioactive decay of an atomic nucleus.
- 5. Dosimeter: A device used to measure exposure to ionizing radiation.
- 7. Fusion: A nuclear reaction in which atomic nuclei combine to form more massive nuclei with the simultaneous release of energy.
- 10. The time required for half of the atoms in a sample of a radioactive substance to decay.
- 11. Atoms of the same element that have the same number of protons but different numbers of neutrons.
- 14. The process of changing one element into another through nuclear reactions.
- 15. Chemistry Vocabulary:
- 16. Fission: A nuclear reaction in which a heavy nucleus splits into smaller nuclei, releasing a large amount of energy.
Down
- 1. The process by which unstable atomic nuclei lose energy by emitting radiation.
- 2. Radiation: Radiation with enough energy to remove tightly bound electrons from atoms, creating ions.
- 4. Mass: The total mass of an atom, which is the sum of the masses of protons, neutrons, and electrons.
- 6. Particle: A type of nuclear radiation consisting of two protons and two neutrons, equivalent to a helium-4 nucleus.
- 8. Number: The number of protons in the nucleus of an atom.
- 9. Activation: The process in which neutron radiation induces radioactivity in materials.
- 12. Counter: A device used to detect and measure ionizing radiation.
- 13. Radiation: High-energy electromagnetic radiation emitted from a nucleus during radioactive decay.
