suppose theres an an electron np1., then on which side of the dumbbell does the electron revolve?

Question

i know that a p-orbital has a dumbell shape and is categorised into
Px, Py, Pz orientations. If an electron is having the configuration of np1, does it revolve around x or y or z orientation?and lets say it rotates at some specific orientation. If the shape of p-orbital is dumbell shaped,that means, theres a common point in the centre (of the dumbell) which is the nucleus which implies the electron travels THROUGH the nucleus. How is it possible?

Answer 1

First the electron would have an sp1 configuration not np1. As to which orbital it would revolve in...it doesn't matter. The x, y, and z are just ways to distinquish the 3 different orbitals. the point in the center is a null point. the electrons do not actually travel through that spot. Orbital configurations just define a volume where an electron might spend some of its time. it could be found anywhere in the volume.

Answer 2

it's just a field of probablity. if the center is the nucleus there's almost no probablity that the electron will be there. as for the rest it's an electron cloud. it's not fixed rotation path.
