Atomic orbitals: 7p radial distribution function

Schematic plot of the 7p radial distribution function 4πr²ψ_7p²

For 7p-orbitals, the radial distribution function is related to the product obtained by multiplying the square of the radial wave function R_7p by r². By definition, it is independent of direction.

All of p-orbitals have one planar node, The 7p radial distribution function shows five radial nodes and the higher p orbitals show more. The number of nodes is related to the principal quantum number, n. In general, the np orbital have (n - 2) radial nodes. Therefore, the 7p-orbital has (7 - 2) = 5 radial nodes, as shown in the above plot. Radial nodes become evident in the higher p-orbitals ( ) while lower p-orbitals (2p, 3p, 4p, 5p, and 6p) show fewer.
