  1. Quantum Physics Quantum Mechanics and atomic structure

  2. Electron probability rather than orbit or trajectory. Probability, not destiny

  3. Diffraction and interference. Wavelength =h/mv Atomic structure is just wave solutions in a potential well. Electron has wave properties Modern Atomic Theory: http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/modern-atomic-theory.html

  4. Electron has wave properties • Diffraction and interference. • Wavelength =h/mv • Atomic structure is just wave solutions in a potential well. • Heisenberg Uncertainty Principle

  5. Problem: theory did not fit shape. Einstein: photons Blackbody radiation
