Atomic orbitals: 5g
For any atom, there are nine 5g orbitals. These orbitals are exotic in the sense that no elements are known in which the 5g orbitals are occupied in their ground states. However these orbitals may be populated in some excited states.
Follow the links towards the base of the page for information about individual orbitals.
The shapes of the nine 5g orbitals. From left to right: (top row) 5gz4, (next to top row) 5gz3x and 5gz3y, (middle row) 5gz2xy and 5gz2(x2 - y2), (next to bottom row) 5gzx3 and 5gzy3, (bottom row) 5gxy(x2-y2) and 5gx4 + y4. For each, the blue zones are where the wave functions have negative values and the red zones denote positive values.
In this set of 5g orbitals, there are five distinct shapes, each of which possess a number of planar and conical nodes. The 5g orbitals do not possess any radial nodes.
The 5gxy(x2-y2) and 5gx4 + y4 (bottom row in the image above) each have ten lobes and are related to each other by a 22.5° rotation about the z-axis. Each orbital has four nodal planes, all of which include the z-axis. For the 5gxy(x2-y2) orbital, these planar nodes are the xz, yz, x=y and x=-y planes.
The 5gzx3 [an abbreviation for 5gxz(x2 - 3y2)] and 5gzy3 [an abbreviation for 5gyz(3x2 - y2)] orbitals (next to bottom row in the image above) each have twelve lobes and are related to each other by a 30° rotation about the z-axis. Each orbital is partitioned by three nodal planes lying at 60° to each other, each lying along the z-axis, and a further nodal plane in the xy plane.
The 5gz2xy [an abbreviation for 5gxy(6z2 - x2 - y2)] and 5gz2(x2 - y2) [an abbreviation for 5g(x2 - y2)(6z2 - x2 - y2)] orbitals (middle row in the image above) each have twelve lobes and are related to each other by a 45° rotation about the z-axis. Each orbital is partitioned by two nodal planes including the z-axis lying at 90° to each other, and a further conical nodal surface.
The 5gz3x and 5gz3y (next to top row in the image above) each have eight lobes and are related to each other by a 90° rotation about the z-axis. Each orbital has a nodal xy plane, and a further nodal plane that includes the z-axis. Finally, each has conical nodal surfaces.
The 5gz4 (top orbital in the image above) has five lobes partitioned by conical nodal surfaces.
