The five d orbitals have l = 2. Four of them are cloverleaf-shaped with four lobes, lying between or along the axes, and the fifth, dz2, has two lobes along the z axis and a ring in the xy plane. There are seven f orbitals with l = 3, and they have more complex multi-lobed shapes with several nodal surfaces. The d orbitals are central to transition metal chemistry, where their partly filled shells give rise to colour, magnetism and catalytic behaviour. Their shapes influence how ligands approach a metal ion.
Key ideas: Five d orbitals: four cloverleaf shapes (dxy, dxz, dyz, dx2-y2) with 4 lobes and 2 angular nodes, and dz2 with a dumbbell and a donut-shaped ring. Seven f orbitals have 3 angular nodes and more complex lobed shapes. In an octahedral complex, d orbitals split into t2g (3) and eg (2) sets.
Common mistakes and connections: Students think dz2 lies in a different form because of an extra dimension; it is a combination of two lobes plus a ring and is equivalent to the others in energy. dx2-y2 lobes lie on the axes, while dxy lobes lie between them. These shapes explain crystal field splitting and transition metal colors.
The 3d orbital shows the four-lobed cloverleaf shape typical of d orbitals, with two nodal planes through the nucleus. The interactive lesson shows this as a live animation or chart.
The dz2 orbital has lobes along the z axis and a doughnut-shaped ring in the xy plane.
