For any atom, there are 7 4f orbitals. The f-orbitals space unusual in that there room two set of orbitals in common use. The an initial set is recognized as the general set, this page. The 2nd set is the cubic set, this page and these can be ideal to usage if the atom is in a cubic environment, because that instance. 3 of the orbitals are typical to both sets. These space are the 4fxyz, 4fz3, and 4fz(x2-y2) orbitals.

The higher f-orbitals (5f, 6f, and also 7f) are more complicated since they have one or much more spherical nodes.

4f atom orbitals general set


The form of the seven 4f orbitals (general set). native left come right: (top row) 4fz3, (next to top row) 4fyz2, 4fxz2, (next come bottom row) 4fxyz, and also 4fz(x2-y2), (bottom row) 4fy(3x2-y2), 4fx(x2-3y2). Because that each, the environment-friendly zones are where the wave attributes have optimistic values and the white zones denote an unfavorable values.

In the general set of 4f orbitals, there room four unique shapes, each of which own a number of planar and conical nodes. The 4f orbitals do not possess any type of radial nodes.

The 4fz3 orbit (top heat in the image above) has a planar node in the xy airplane and two conical nodes with their exes along the z-axis.

The 4fyz2 and also 4fxz2 orbitals (next to optimal row in the image above) are concerned each various other by a 90° rotation about the z-axis. At an initial sight, castle are comparable in form to the 4fy(3x2-y2) and also 4fx(x2-3y2) orbitals however they are not. While this orbitals contain six lobes, the nodal planes space not in ~ 60° to every other and two the the 6 lobes room "bean-shaped".

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

The 4fy(3x2-y2) and 4fx(x2-3y2) orbitals (bottom row in the image above) are pertained to each various other by a 90° rotation around the z-axis. Each orbital has actually six lobes be separated by three nodal plane lying at 60° to each other.

4f atomic orbitals cubic set

The shape of the 7 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. Because that each, the green zones are where the wave features have hopeful values and the white area denote an unfavorable values.

In the cubic set of 4f orbitals, there room two distinctive shapes, each of which possess a variety of planar and also conical nodes. No one of the 4f orbitals own radial nodes.

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

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