Nodal Planes

Postby Clara Cho 2K » Fri Oct 18, 2019 11:57 am

Can someone explain what nodal planes are?

Nodal planes are any areas where the is zero probability of electron density. Therefore, there will be no electrons in that area.

A nodal plane is a plane where there are no electrons (zero percent chance of finding an electron there). An example is the 2p orbital!

Nodal planes are the areas where the probability of finding electrons is zero. The two types of nodal planes are radial nodes and angular nodes.

I understand that nodal planes are areas where there is zero probability of electron density, but how does this relate to symmetry?

Can someone explain why s has no nodal plane? thanks!

if atoms with more electrons have more places where electrons can be found, why does this also increase the amount of nodal planes in that atom?

electron pair repulsion creates gaps

electrons push each other away, more electrons means more pushing each other way until they shape the orbitals, more orbitals means more chances for nodal planes to exist between them

there aren't enough electrons that exist within that orbital to form nodes in which case a plane would form, electrons can exist wherever they want within the spherical s orbital

Adding on,

P and D orbitals have a nodal plane, zero electron density (non-symmetric)
S orbitals have no nodal planes (symmetric electron distribution)
