How does one determine the location of an atom's electrons using the quantum theory?
Due to Heisenberg's uncertainty principle one can never know the position of an electron to an arbitrary precision. We can only use quantum mechanical probability densities to estimate it's position. Or we can measure it's location, but that only tells us where it was and can not tell us where it is or how fast it is moving.

How does the quantum mechanical model describes energies?
According to the modern theory of quantum mechanics the electrons have a vibrating wave character and hence uncertain positions.Sometimes,they are close to the nucleus and sometimes away from it.Thus we can say that the paths of motion of electrons around the nucleus are not definite
Who developed the quantum theory of the nuclear atom?
Heisenberg and Schrodinger developed the electron cloud model using quantum mechanical probability functions to determine the the regions, or clouds, in which electrons would most likely be found outside of the nucleus.
Which particle is most involved with quantum theory?
The electron is the particle most involved with quantum theory. Its behavior and properties are governed by quantum mechanics, which describes the behavior of very small particles like electrons.
How many electrons have quantum numbers values n l m?
In theory, the number of electrons with each quantum number is not limited. However, for any given "main quantum number" (n), the number of electrons having the other quantum numbers is limited - but it depends on the value of "n". For more information, the Wikipedia article on "quantum number" seems to give a good overview.
What is the main difference between Classical free Electron theory and Quantum free Electron theory?
Electrons are fermions and thus cannot occupy the same quantum states. They obey Fermi-Dirac statistics, and will occupy energy levels accordingly. This is different to the classica state where all electrons are pretty much equal (equal energies etc) and are not taken to be distrubuted amongst multiple states and energies. See Fermi Gas Model for a treatment of quantum free electron theory.

What are the three main parts of an electrons address used in the current atomic theory that describe an electrons location?
I think you are referring to the 3 quantum numbers, n, l m; principal azimuthal and magnetic. Together with the spin quantum number they "define" an electron- but I would hesitate to call this the electrons location- Heisenbergs uncertainty principle gets in the way of a simultaneous knowledge of energy and location.
Who discovered the theory of electrons and quantum mechanics?

What is quantum free electron theory of metal?
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
What is the electron movement thought to be in the quantum mechanical theory?
In quantum mechanical theory, electron movement is described not as a definite path but as a probability distribution around the nucleus, often represented by orbitals. Electrons exist in discrete energy levels, and their exact position cannot be pinpointed; instead, we can only determine the likelihood of finding an electron in a specific region of space at a given time. This behavior is a fundamental aspect of quantum mechanics, reflecting the wave-particle duality of electrons.

What model do scientists use today to describe how electrons move around the nucleus?
Scientists use the quantum mechanical model to describe how electrons move around the nucleus. This model takes into account both the wave-like and particle-like properties of electrons, providing a more accurate description of their behavior within an atom. It uses mathematical equations based on the principles of quantum mechanics to determine the probability of finding an electron at a given location around the nucleus.
