For any atom, there are seven 4f orbitals. The f-orbitals are unusual in the there space two set of orbitals in typical use. The very first set is recognized as the general set, this page. The second set is the cubic set, this page and these could be appropriate to use if the atom is in a cubic environment, for instance. 3 of the orbitals are usual to both sets. These space are the 4fxyz, 4fz3, and 4fz(x2-y2) orbitals.

The greater f-orbitals (5f, 6f, and also 7f) room more facility since they have one or more spherical nodes.

The shape of the 7 4f orbitals (general set). indigenous left come right: (top row) 4fz3, (next to height row) 4fyz2, 4fxz2, (next come bottom row) 4fxyz, and 4fz(x2-y2), (bottom row) 4fy(3x2-y2), 4fx(x2-3y2). Because that each, the eco-friendly zones space where the wave features have hopeful values and also the white zones denote negative values.

In the general set of 4f orbitals, there room four unique shapes, each of which possess a variety of planar and also conical nodes. The 4f orbitals execute not possess any kind of radial nodes.

The 4fz3 orbital (top heat in the picture above) has a planar node in the xy plane and 2 conical nodes with their exes along the z-axis.

The 4fyz2 and also 4fxz2 orbitals (next to top row in the photo above) are pertained to each other by a 90° rotation around the z-axis. At first sight, lock are comparable in form to the 4fy(3x2-y2) and also 4fx(x2-3y2) orbitals but they are not. While these orbitals contain six lobes, the nodal planes are not at 60° to each other and also two that the six lobes space "bean-shaped".

The 4fxyz and also 4fz(x2-y2) (next to bottom heat in the image above) each have eight lobes and are related to each various other by a 45° rotation about the z-axis. Every orbital has three nodal planes, which because that the 4fxyz room the xy, xz, and also yz planes.

The 4fy(3x2-y2) and also 4fx(x2-3y2) orbitals (bottom heat in the image above) are regarded each other by a 90° rotation about the z-axis. Each orbital has actually six lobes be separated by 3 nodal airplane lying in ~ 60° to each other.

4f atomic orbitals cubic set

The form of the seven 4f orbitals (cubic set). indigenous left come right: (top row) 4fy3, 4fz3, 4fx3, (middle row) 4fy(z2-x2), 4fz(x2-y2), and also 4fx(z2-y2)(bottom row) 4fxyz. For each, the eco-friendly zones are where the wave features have positive values and also the white zones denote negative values.

In the cubic set of 4f orbitals, there space two unique shapes, each of which possess a variety of planar and conical nodes. None of the 4f orbitals own radial nodes.

The 4fxyz, 4fx(z2-y2), 4fy(z2-x2), and 4fz(x2-y2) (bottom 2 rows in the image above) each have eight lobes. The 4fx(z2-y2), 4fy(z2-x2), and also 4fz(x2-y2) orbitals are pertained to each other by 45° rotations about the x, y, and z-axis respectively. Each orbital has three nodal planes, which for the 4fxyz are the xy, xz, and also yz planes.

The 4fx3, 4fy3, and also 4fz3 orbitals (top heat in the image above) has actually a planar node in the xy aircraft and 2 conical nodes orientated along the z-axis. The various other two orbitals are connected through 90° rotations.
