Quantum shell theory was first proposed by the physicist Niels Bohr as an explanation of the unexpected complexity of the spectra of hydrogen and various other atoms. According to Bohr each quantum shell represents a certain state of energy, attributed to the electron orbiting within that shell. So an electron within the lowest shell would be orbiting at the orbit closest to the nucleus, and thus has the least energy, whereas an electron within a higher shell would be orbiting at the next closest orbit to the nucleus, and thus has a bit more energy by a discrete amount as given by Planck. However, it was noted that this explanation, although it worked perfectly with hydrogen, became more and more inaccurate as the Atomic Mass of the element in question increased. Therefore, later the electrons and nucleic particles in Bohr's quantum shell theory, with its discrete, pointlike particles, was augmented by another description from wave mechanics, based on Schrodinger's equation, that envisioned Bohr's discrete particles as a sort of vibrating instrument- although what exactly it is that vibrates, and what exact relation it bears to the particle, did not seem to be clear at the time (and is still ambiguous to some extent now). After the assertions of wave mechanics were successfully tested (such as the predicted diffraction of electrons etc.), its description was recognized for the wonder it was, and nowadays replace quantum shell theory as a more accurate and complete description for the working of the atom. This is not to say, however, that quantum shell theory was disproved, just as the dawn of relativity does not disprove Newtonian mechanics. All the modern quantum mechanics, with its powerful wave equation, has done was to replace Bohr's more naive view with a more mature, complete and accurate understanding of the working of the atom. The fact that Bohr was superseded does not mean he was wrong, merely that his description was not complete or nearly accurate enough to account for the phenomena observed. Even now, because of the simpler maths, it's still used as a introduction to the weird wonders of the quantum world.
This is a tough question to answer, but in general yes. The principles hold very firmly such that we are able to make devices based on them. For example a flash drive (thumb drive) utilizes QM principles in such a way that if QM was wrong there is no way that device would exist.
The formula for getting the total number electrons occupying a shell is given by 2n2 For M shell the principal quantum number, that is, 'n' is 3. So 2 x 9 = 18 For N shell its quantum number is 4 and hence 32 electrons.
The space is referred to as a shell. Within the shell there is the subshell (orbit) and then there is the orbital (the orientation in 3D space)
The quantum mechanical model is called the quantum theory.
Andreas Vesalius
The most known theory in quantum mechanics would be the Broglie-Bohm theory. Other popular theories are the string theory, quantum entanglement, and SchrÌ_dinger's cat.
Claudius Ptolemy disproved geocentric theory.
vital theory was disproved by mr shianrilong reamei
Certainly. Many theories are disproved. A disproved theory will either be reworked based on the information obtained while disproving it or will be discarded.
Thomson disproved Dalton's theory because he discovered electrons.
A. S. Davydov is known for his work in the field of theoretical physics, particularly in the area of subnuclear particles and quantum field theory. He is most recognized for his contributions to the development of the nuclear shell model.

The original founder of quantum theory was Max Plank. The basic theory has been improved upon many times but there hasn't been a 'Modern Quantum Theory' that replaces the old.
