Atomic orbitals: sp3 hybrid electron density

Schematic plot of a sp3 electron density function. Blue represents negative values for the wave functions and red represents positive values.

The "surface" of the orbital represents points for which the electron density for that orbital is the same - an isosurface. By choosing different values of electron density, denoted by the bar moving up and down on the line plot or by the moving plane on the surface plot, then the size of the three-dimensional plot changes.

The plot above is represents one of the four sp3 orbitals but the form of the others is similar, differing only in orientation.

All values are of necessity not negative since the square of any real number cannot be less than zero.
