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 wavelengthChanged the Bohr model so that all elements could be explained according to their frequencies of energy.
6 De BroglieEssentially the model went fromde BroglieBohrto
7 Schrodinger (and his cat) A thought experimentSimultaneous existence
8 Heisenberg Uncertainty Principle An electron’s 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.
