28.1.2—Sketch the shape of a 3dxy orbital and 3dz²

Syllabus
9701–2028–2029
Objective
28.1.2
Level
A2

The 3d orbitals differ in orientation but have the same energy in an isolated atom

The dxy orbital has four lobes lying between the x and y axes in the xy plane. The dz² orbital has two lobes along z with a torus around the centre.

All five d orbitals have the same general four-lobed/axial angular family in an isolated atom, but their orientations differ. In a ligand field, their energies can split.

Sketch axes first, then place dxy lobes between axes and dz² lobes on the z axis with the doughnut in the xy plane.

Do not put dxy lobes on the axes or draw dz² as a simple p orbital.
