# Atomic orbitals: 6f (cubic set)

For any atom, there are seven 6f orbitals. The f-orbitals are unusual in that there are two sets of orbitals in common use. Those shown here are the cubic set and these are appropriate to use if the atom is in a cubic environment, for instance. The other set is known as the general set. Three of the orbitals are common to both sets. These are are the 6fxyz, 6fz3, and 6fz(x2-y2) orbitals.

In the cubic set of 6f orbitals, there are two distinct shapes, each of which possess a number of planar and conical nodes. Each of the 6f orbitals possess two radial nodes.

The 6fxyz, 6fx(z2-y2), 6fy(z2-x2), and 6fz(x2-y2) (bottom two rows in the image above) each have eight lobes. The 6fx(z2-y2), 6fy(z2-x2), and 6fz(x2-y2) orbitals are related to each other by 45° rotations about the x, y, and z-axis respectively. Each orbital has three nodal planes, which for the 6fxyz are the xy, xz, and yz planes.

The 6fx3, 6fy3, and 6fz3 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 other two orbitals are related through 90° rotations.
