In quantum physics and chemistry, quantum numbers are quantities that characterize the possible states of the system. To fully specify the state of the electron in a hydrogen atom, four quantum numbers are needed. The traditional set of quantum numbers includes the principal, azimuthal, magnetic, and spin quantum numbers. To describe other ...

As a tool for physics, quantum states grew out of states in classical mechanics. A classical dynamical state consists of a set of dynamical variables with well-defined real values at each instant of time. [1]: 3 For example, the state of a cannon ball would consist of its position and velocity. The state values evolve under equations of motion ...
A common example of quantum numbers is the possible state of an electron in a central potential: (,,,), which corresponds to the eigenstate of observables (in terms of ), (magnitude of angular momentum), (angular momentum in -direction), and .

A quantum state in the Fock space is called a Fock state if it is an element of the occupancy number basis. A Fock state satisfies an important criterion: for each i , the state is an eigenstate of the particle number operator N k i ^ {\displaystyle {\widehat {N_{{\mathbf {k} }_{i}}}}} corresponding to the i -th elementary state k i .
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
This table gives the name, quantum numbers (where known), and experimental status of baryons resonances confirmed by the PDG. [41] Baryon resonance particles are excited baryon states with short half lives and higher masses.
