Nuclear Chemistry
Across
- 3. life, the amount of time it takes for half of a sample to decay
- 6. protons and neutrons
- 7. that can be stopped by clothing
- 9. nuclear force, keeps protons attracted to each other in the nucleus
- 10. a positive electron
- 12. when one atom turns into a different atom
Down
- 1. an atom in nuclear chemistry
- 2. radiation that can only be stopped by lead
- 4. radiation that can be stopped with aluminum foil
- 5. when two small nuclei combine to form a larger nucleus creating a lot of energy
- 8. when an atom is unstable and decays
- 11. when one large nucleus splits into two smaller nuclei creating a lot of energy
