Particle Physics
Across
- 3. created the cloud chamber
- 4. negatively charged, orbits the nucleus
- 5. created a periodic table based on common chemical properties
- 7. enter our atmosphere from outer space and trigger a chain of particle interactions
- 9. accelerate ordinary stable particles (e, p) from rest to large kinetic energies and smash them into the other matter
- 11. means "indivisible"
- 12. experimented with “neutral” cathode rays
- 14. makes up protons and neutrons
Down
- 1. produces energetic beams which allow us to probe matter at its most fundamental level
- 2. positively charged in the nucleus
- 6. found a nucleus in the atom by firing alpha particles at gold and observing them bounce back
- 8. divided matter into four (five) elements
- 10. discovered the neutron
- 13. no charge in the nucleus
