Atomic Theory

5. Model that said the atom was mostly the same consistency throughout with electrons scattered throughout.
6. Came up with the "Quantum Mechanical Model" of the atom (also known for his kitty)
9. The number of protons in the nucleus.
10. Millikan's experiment that showed the size of a charge on an electron.
13. Model that said atoms were just hard spheres.
16. Who discovered atoms?
17. Rutherford's model where most of the atom's mass was in its nucleus and electrons orbited it (aka Planetary Model).
18. Particle with no charge.
19. Who discovered the neutron?
20. Made up of protons and neutrons.

1. Said there's a fundamental limit to what we can know about the behavior of quantum particles.
2. Who discovered the electron?
3. Bohr's model of an atom that said electrons could jump to different orbits.
4. Positively charged particle.
7. Negatively charged particle.
8. Created the "Billiard Ball Model" of an atom.
11. Model that said that it’s impossible to simultaneously know the exact position and momentum of a particle.
12. The regions around an atom that are most likely to contain electrons.
14. Rutherford's experiment that showed the mass of the nucleus was 10,000 times smaller than the atom itself.
15. Average mass of the atom.
