AP Chemistry By Diane Paskowski
2
If light is a wave with particle properties, are electrons particles with wave properties? C. J. Davisson and L. H. Germier at Bell labs proved that electrons produce diffraction patterns and verified deBroglies hypothesis
3
Bohr’s model did not work for atoms other than hydrogen Werner Heisenberg and Erwin Schrodinger developed quantum mechanics independently.
4
Schrodinger ◦ Emphasized wave properties of the electrons ◦ Wave function
6
Orbital is not an orbit Electron NOT moving around the nucleus DO NOT KNOW how it is moving
7
Heisenberg Uncertainty Principle ◦ There is a fundamental limitation to just how precisely we can know both the position and momentum of a particle at a given time.
8
Wave function has no easily visualized physical meaning Square of the function indicates the probability of finding an electron near a particular point in space Probabilty distribution defines the orbital
