In quantum physics and chemistry, quantum numbers are quantities that characterize the possible states of the system They represent the position, movement, and energy of the fundamental particle. 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. Quantum numbers are a set of numbers used to define the state in which a fundamental particle like an atom, ion, nucleus, and electron resides Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons
