In a p-orbital how does an electron travel from lobe to another if it must cross the nodal plane which has no electron density?
Redbelly98 said:Welcome to PF!
It doesn't travel from one lobe to another, it is simultaneously in both lobes. More precisely, it has nonzero probability of being in each lobe, at every moment.
ldv1452 said:Thanks you. I'm still a little unclear on this. Is it that the electron does not actually travel through space? Or just that we can not determine its position so we rely on probability?
alxm said:Well this is somewhat of an interpretation issue. But the usual view is that it's position is indefinite. The electron is 'moving', in the sense that it has kinetic energy (and some other properties of motion) however it is not moving in the classical sense where it has a definite position and momentum at every point in time.
ldv1452 said:This is very interesting. So are you saying that at a given point in time an electron may not have a position (in the sense that it physically is not anywhere) or that it has no "position" per say because we can not determine it? And if its the former then where is the electron at that point in time?

I like that.alxm said:In fact, as far as we know, the wave function tells us everything that we can know about it)
Electrons in a p-orbital move in a specific pattern known as a dumbbell shape. This means that the electron moves back and forth between two regions of space, with a node at the center where the electron has no probability of being found.
The energy level of an electron in a p-orbital depends on its distance from the nucleus. The closer an electron is to the nucleus, the lower its energy level. Each p-orbital can hold a maximum of two electrons, with one electron in the higher energy level and one in the lower energy level.
Each energy level has three p-orbitals, labeled as px, py, and pz. These orbitals are oriented along the x, y, and z axes, respectively.
An electron can transition between p-orbitals by absorbing or emitting a photon of electromagnetic radiation. This causes the electron to jump to a higher or lower energy level, depending on the direction of the transition.
A p-orbital has a dumbbell shape, with two lobes on either side of a central node. The size and orientation of the lobes vary depending on the energy level and sublevel of the orbital.
