Quantum Mechanics of the Electron

Guided Notes

3 key concepts

  • 1

    De Broglie suggested that if waves can behave like particles, then particles must also behave like waves, meaning all matter has a wavelength.

  • 2

    Schrödinger developed quantum mechanics to describe the wave mechanics of the electron, leading to the understanding that electrons exist as a cloud of probability density.

  • 3

    Heisenberg's uncertainty principle states that the more we know about an electron's location, the less we know about its momentum, and vice versa, which is an inherent quality of the electron.
