This principle forms the basis of the electron cloud model. Thus we see that an electron cloud model is a visual model that gives the probable locations of electrons in an atom. In this model, electrons are not shown as particles moving around the nucleus in a fixed orbit. It is a modern and the most accepted atomic model, and has rendered all previous explanations of the atomic structure obsolete. Erwin Schrodinger, an Austrian physicist came up with the electron cloud model in 1926.
Electron cloud model. One model of the atom states that instead of electrons being tiny particles in orbits, they are in the form of an electron cloud in shells around the nucleus. This model is due to the Uncertainty Principle and is useful in Quantum Mechanics.he Bohr model or solar system model of the atom is that the atom is like a tiny solar system, with the nucleus in the center and electrons rotating around the nucleus in orbits, similar to how the planets rotate around the Sun.
