Hence we may tabulate the three quantum numbers n,l, and mtogether with their
permissible values as follows:

Principal quantum number n1, 2, 3,

Orbital quantum number l0, 1, 2, , (n1) (6.17)
Magnetic quantum number ml0, 1, 2, , l

It is worth noting again the natural way in which quantum numbers appear in quantum-
mechanical theories of particles trapped in a particular region of space.
To exhibit the dependence of R, , and upon the quantum numbers n,l,m, we
may write for the electron wave functions of the hydrogen atom

Rnl (^) lml (^) ml (6.18)
The wave functions R, , and together with are given in Table 6.1 for n1, 2,
and 3.
