Bohr
The model of the atom based on Quantum Theory is often called the "Quantum Mechanical Model" or the "Quantum Model." This model describes the behavior of electrons around the nucleus as probabilistic, rather than in fixed orbits.
Today the model of atom is based on quantum mechanics.
Quantum Theory
B, Quantum Theory!
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
Bohr.
The quantum mechanical model of the atom, also known as the electron cloud model, shows electrons as existing in certain regions of space called orbitals. These orbitals represent the probability of finding an electron in a specific location around the nucleus.
The atomic model of Bohr is not a quantum model.
In a sense Niels Bohr did by introducing different orbits in which electrons spin around the nucleus. Bohr argued that each electron has a certain fixed amount of energy, which corresponds to its fixed orbit. Therefore, when an electron absorbs energy, it jumps to the next higher orbit rather than moving continuously between orbits. The characteristic of electrons having fixed energy quantities (quanta) is also known as the quantum theory of the atom.
The current picture of the hydrogen atom is based on the atomic orbitals of wave mechanics which Erwin Schrodinger developed in 1926. This model is based on the Schrodinger Equation.
The most accurate, but not user friendly and usable model is the quantum mechanic atom model (QM model)
Niels Bohr worked in the field of physics, with a focus on atomic structure and quantum theory. He made significant contributions to the development of the theory of quantum mechanics and is best known for his model of the atom, called the Bohr model.
