During the 1920s Austrian physicist Erwin Schrödinger (1887-1961) introduced what came to be known as the wave mechanical model, also known as the particle-wave hypothesis.

The modern atomic model is based on quantum mechanics.
Bohr.
In 1913 he gave us the Bohr Model to explain the Rydberg formula for spectral emissions.
Introduced by Niels Bohr in 1913, the model's key success lay in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen.The Bohr model is a primitive model of the hydrogen atom. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics, and thus may be considered to be an obsolete scientific theory. However, because of its simplicity, and its correct results for selected systems , the Bohr model is still commonly taught to introduce students to quantum mechanics, before moving on to the more accurate but more complex valence shell atom.
The quantum mechanical model is called the quantum theory.
Today the model of atom is based on quantum mechanics.
The Bohr Model, and its the basis of quantum theory
The modern atomic model is based on quantum mechanics.
No, it is not necessary.
A Schrodinger atomic model doesn't exist; you think probable to quantum mechanics.
Well, the conventional system of quantum mechanics can also be known as the Standard Model of Particle Interaction, or the Standard Model for short.
Erwin Schrodinger
He was a physicist that is most known for working with quantum mechanics. Schrodinger's cat was his thought on the uncertaintiness of the modern model of quantum mechanics. The cat was either dead or alive but also neither.
String theory is one of the leading candidates for a theory of everything, that is, a theory that unifies all 4 basic forces of nature, viz, gravity, the electromagnetic force, the strong force and the weak force. The last 3 forces mentioned above are described by quantum mechanics. This is the link between quantum mechanics and string theory. ps- If you believe in watertight definitions, then quantum mechanics is all the quantum theory till Dirac's equation. I'm taking quantum mechanics as the theory of the small as such, that is, all of the phenomena of the small from Plank till the standard model and beyond.
Bohr.
A dense nucleus of protons and neutrons surrounded by electron clouds of different shapes and sizes.
Sommerfield's model is a semi quantum-mechanics, a classical free electron model. However, it differs from the Drude's model since it is incorporate in a quantum mechanics idea such that : - Only discrete energy levels are allowed for the electron. - Together with the Pauli Exclussion Principle and Fermi-Dirac statistic which deal with the probability of occupancy of the energy states by electron. - The density of available states for the electron occupancy.
