Document Summary

Principal quantum number n: (cid:374) = (cid:1005), (cid:1006), (cid:1007), (cid:894)relates to e(cid:374)ergy a(cid:374)d (cid:373)ost pro(cid:271)a(cid:271)le dista(cid:374)(cid:272)e of a(cid:374) ele(cid:272)tro(cid:374) fro(cid:373) the (cid:374)u(cid:272)leus(cid:895) Orbital angular momentum quantum number l l = (cid:1004), (cid:1005), (cid:1006), (cid:894) (cid:374)-1) (relates to shape of the orbital) Magnetic quantum number m l: ml = - l, -l + 1, -l +(cid:1006), (cid:1004) l - 2 , l - 1, l (relates to orientation of the orbital) We use a shorthand to describe the orbitals n defines the principal electronic shell and we keep the number: within each principal shell there are other possible sub-shells (as l varies) When l = 0 we call the subshell s. When l = 1 we call the subshell p. When l =2 we call the subshell d. When l =3 we call the subshell f. Whe(cid:374) l = (cid:1004), (cid:373) l = (cid:1004) so there is (cid:1005) (cid:862)s(cid:863) or(cid:271)ital.
