6s atomic orbital

The shape of the 6s 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 6s 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 five spherical nodes of the 6s orbital. The shape on the right shows the nodal structure of the 6s-orbital.

While still spherical, the higher s-orbitals (such as the 7s) are more complex since they have more spherical nodes. While still spherical, the lower s-orbitals ( 5s, 4s, 3s, 2s, and 1s) are simpler since they have fewer spherical nodes.
