Detailed explanation-1: -Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Detailed explanation-2: -Quantum mechanics is the branch of physics that deals with the behavior of matter and light on a subatomic and atomic level. It attempts to explain the properties of atoms and molecules and their fundamental particles like protons, neutrons, electrons, gluons, and quarks.

Detailed explanation-3: -Quantum mechanics models describe the possibility of placing electrons within an atom by describing the principal energy level, energy level, orbital (arbitrary level), and spin of. The quantum mechanics model is based on quantum theory, which states that matter has wave-like properties.
