Nuclear, Atomic, and Particle Physics
- Discrete energy and radioactivity
Discrete energy
-
It emits lights of varying wavelengths, the possible wavelengths are called emission spectrum
This is because the energies of the atoms are discrete and can change between the states by emitting a photon

Atomic Models
Plum pudding model:
- Invented by JJ Thompson
- Discovered electrons, or negatively charged particles attracted to positively charged particles
- Argued that electrons were like pieces of "plum" in a greater positively charged mass "pudding"
Rutherford model:
- Discovered the existence of the nucleus
Supported the idea that electrons orbited the nucleus, however did not describe the patterns in which they
-
Dalton Model:
- First model of atom
- Argued that atoms were hard spheres, the smallest amount of matter that retained all physical properties
