The Quantum Model Part II Energy as wave and particle
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.
De Broglie Essentially the model went from de Broglie Bohr to
Schrodinger (and his cat) A thought experiment Simultaneous existence
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.
