7s atomic orbital

...

The shape of the 7s orbital. The blue zone is where the wave function has positive values while the white zone is where values are positive.

For any atom there is just one 7s orbital. The image on the top is deceptively simple as the interesting feature is buried within the orbital. That on the left is sliced in half to show the six spherical nodes of the 7s orbital. The shape on the right shows the nodal structure of the 7s-orbital.

While still spherical, higher s-orbitals (8s, 9s ...) are more complex since they have more spherical nodes. While still spherical, the lower s-orbitals ( 6s, 5s, 4s, 3s, 2s, and 1s) are simpler since they have fewer spherical nodes.
