1 Waves: A Warm up How many wavelengths are represented in each figure below?

2 The Electromagnetic Spectrum

3 The Periodic Table 1s 2s2p 3s3p 4s3d4p 5s4d5p 6s5d6p 7s6d7p 4f 5f

4 The Quantum Model Part II Energy as wave and particle

5 De Broglie Small matter (electrons) have wavelike properties as well. Any moving particle has a wavelength Changed the Bohr model so that all elements could be explained according to their frequencies of energy.

6 De Broglie Essentially the model went from Bohr to de Broglie

7 Schrodinger (and his cat) A thought experiment Simultaneous existence

8 Heisenberg Uncertainty Principle An electrons location and speed cannot be determined at the same time. If we cause change to find one variable, we are no longer looking at the actual e - situation. So quantum mechanics can tell us the probability that an electron is somewhere, but it does not tell us how it got there.
