Apart from the planar node there is also a spherical node that partitions off the small inner lobes. A p orbital has the approximate shape of a pair of lobes on opposite sides of the nucleus, or a somewhat dumbbell shape. An electron in a p orbital has equal probability of being in either half.

Emily Oneal. We can calculate how many nodes there will be based off the equation above, however we can also see this from the wavefunction. For example the wavefunction for the Hydrogen atom 3d orbital:. As stated above, we know that at a node the probability of finding an electron is zero.
The diagram below shows that as n increases, the number of radial nodes increases. To separate the wavefunction into a radial part and an angular part, the system needs to be spherically symmetric. For an atom this is the case but a molecule can never be. Thus radial nodes do not exist for molecular orbitals. Introduction There are two types of nodes within an atom: angular and radial. Figure 1: Various s orbitals. Basic description To solve for the number of radial nodes, the following simple equation can be used.
Advanced description We can calculate how many nodes there will be based off the equation above, however we can also see this from the wavefunction.
Figure 2: The radial probability distribution of finding an electron in the 1s, 2s and 3s orbitals. For each S orbital, the probability of finding an electron is zero when r equals zero and as r goes to infinity. But what about for molecular orbitals?
