Electron cloud model

In the 1920s, Louis de Broglie, Erwin Schrödinger, and Werner Heisenberg developed the electron cloud model of the atom. De Broglie proposed that electrons have wave-like properties, while Heisenberg established that the exact location and momentum of a particle cannot be known simultaneously. Schrödinger then created mathematical equations to predict the probability of finding electrons in certain regions or orbitals, rather than fixed orbits. This led to the concept of an electron cloud showing the probable locations of electrons around the nucleus.

- 3. de Broglie: Electrons have wavelike properties. Heisenberg: It is impossible to know both the location of a particle and how a particle is moving. With small particles (like electrons) this means we will never be able to say exactly where an electron is located. Schrödinger: Developed mathematical equations to predict the most likely location of electrons. The Big Ideas
- 4. Electrons exist in certain energy levels as suggested by Bohr but they are not circular orbits. Probability is used to predict where electrons can be found. Electrons are instead found in orbitals. An orbital is a region around nucleus where you are most likely to find an electron. An electron cloud is a visual model of the most likely locations to find an electron around an atom. The Electron Cloud Model
