Jul 27, 2006 · The p orbital is a dumbbell-shaped or lobed region describing where an electron can be found, within a certain degree of probability. The node of the dumbbell occurs at the a tomic nucleus, so the probability of finding an electron in the nucleus is very low (but not zero). The shape of the orbital depends on the quantum numbers associated with an energy state.

The first group contains dxy, dxz, and dyz with each lobes aiming between the two of the axes. The second group contains dx2–y 2, and dz2 with lobes pointing at different axes. It determines the concentration of electron density based on these five axes. The shape of the d orbitals, four out of the fives are similar. These four take the shape of a cloverleaf while the fifth one dz2 assumes the shape of a doughnut with the electron cloud in the centre. However, it has been established that the energy level of the five d orbitals is the same.
