1s wave function and nodal structures

This page illustrates the 1s wave function and its nodal structures. See the 1s electron density page for information about its electron density.

Movie illustrating the 1s wave function ψ_1s. Blue represents positive values for the wave function and white represents negative values (but there are none for the 1s orbital). The two-dimensional graph on the left is a surface plot of ψ_1s on a slice drawn through the nucleus while the plot on the right shows values along a single line drawn through the nucleus.
