Wave model
The wave model of the atom uses the basic idea of the Bohr model of the atom, where there is a small, dense nucleus surrounded by electrons, but the electrons are represented by a probability distribution, instead of by discrete mathematical points. Thus, they are often described as the "electron cloud". This model is based on wave mechanics.

- Quote: (http://members.tripod.com/mwolff/see.html) "...Actually, in the H atom both the electron wave-structure and the proton have the same center. The electron's structure can be imagined like an onion - spherical layers of waves around a center. The amplitude of the waves decreases like the blue standing wave in the bottom diagram. There are no point masses - no orbits, just waves..."
