What purpose do quantum numbers serve?

Question

What purpose do quantum numbers serve?

Answer 1

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 can have one or more quantum numbers, it is a futile job to list all possible quantum numbers.

Answer 2

obviously nothing in volleyaball... wrong section =/

Answer 3

how does this belong in volleyball?

anyways

n: primary energy level

l: shell (s,p,d,f)
