One other p orbital, the 3pz, is shown so
that you can see how orbitals of a given type change as we go to
higher principal quantum numbers. In this orbital most of the
electron density is in the two outer lobes of the orbital, but
there is some electron density in the two small inner lobes.
Remind yourself that this is all one orbital, not several
orbitals. This orbital has cylindrical symmetry, as do all p
