quantum number
notation for conserved quantities in physics and chemistry
principal quantum number
one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state
total angular momentum quantum number
quantum number describing the total angular momentum of an atom
good quantum number
quantum number that doesn't change for any eigenstate as time progresses
azimuthal quantum number
quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital, and is symbolized as ℓ
color charge
property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics
charm
flavour quantum number representing the difference between the number of charm quarks and charm antiquarks that are present in a particle
charge
generalization of electric charge (EM) adding color charge (QCD), mass-energy (gravitation), etc.; sometimes considered same as its charge quantum number
baryon number
one third of the difference between the number of quarks and antiquarks in a system
lepton number
conserved quantum number representing the number of leptons minus the number of antileptons in an elementary particle reaction
flavour
type of elementary particles occurring in the Standard Model
magnetic quantum number
third in a set of four quantum numbers that distinguishes the orbitals available within a subshell and can be used to calculate the azimuthal component of the orientation of orbital in space
multiplicative quantum number
type of quantum number
spin quantum number
quantum number parameterizing spin and angular momentum
topological quantum number
physical quantities that take discrete values because of topological quantum physical effects
strangeness
property of subatomic particles; the number of strange antiquarks minus strange quarks
