1Principal quantum number — In atomic physics, the principal quantum number symbolized as n is the first of a set of quantum numbers (which includes: the principal quantum number, the azimuthal quantum number, the magnetic quantum number, and the spin quantum number) of an… …
2principal quantum number — noun : an integer associated with the energy of an atomic electron in any one of its possible stationary states and including both the azimuthal and the radial quantum number called also total quantum number * * * Physics. the nonnegative,… …
3principal quantum number — Physics. the nonnegative, integral quantum number that defines the stationary orbits in the Bohr model of the atom. Also called total quantum number. [1920 25] * * * …
4Quantum number — Quantum numbers describe values of conserved numbers in the dynamics of the quantum system. They often describe specifically the energies of electrons in atoms, but other possibilities include angular momentum, spin etc.Since any quantum system… …
5quantum number — Physics. 1. any integer or half of an odd integer that distinguishes one of the discrete states of a quantum mechanical system. 2. any number that distinguishes among different members of a family of elementary particles. [1915 20] * * * ▪… …
6Azimuthal quantum number — The azimuthal quantum number (or orbital angular momentum quantum number, second quantum number) symbolized as ℓ (lower case L) is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the… …
7Magnetic quantum number — In atomic physics, the magnetic quantum number is the third of a set of quantum numbers (the principal quantum number, the azimuthal quantum number, the magnetic quantum number, and the spin quantum number) which describe the unique quantum state …
8Spin quantum number — In atomic physics, the spin quantum number is a quantum number that parameterizes the intrinsic angular momentum (or spin angular momentum, or simply spin) of a given particle. The spin quantum number is the fourth of a set of quantum numbers… …
9azimuthal quantum number — noun : an integer associated with the angular momentum of an atomic electron in any one of its possible stationary states, each state corresponding to a different integer compare principal quantum number, radial quantum number * * * Physics. the… …
10azimuthal quantum number — Physics. the quantum number that designates the orbital angular momentum of a particular quantum state of an electron in an atom and that assumes integral values from zero to one less than the value of the principal quantum number. Also called… …
