# Atomic orbitals 5d electron density

This page contains movies depicting the 5dxy, 5dxz, 5dyz, and 5dx2-y2 wave functions. In all cases the red zones are where the 5d wave function has positive values and the white zones denote negative values. See the 5d wave function page for movies depicting the 5d the wave functions and nodal structures.

The "surface" of the three-dimensional orbital at the top centre of each movie 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. All values of electron density are of necessity not negative since the square of any real number cannot be less than zero.

## 5dz2 orbital electron density

Movie depicting the 5dz2 electron density function (ψ5dz2)2. The z-axis lies from left to right.

The 5dz2 orbital has two conical nodes two spherical nodes. The higher d-orbitals ( 6d, and 7d) have more while the lower orbitals (3d and 4d) have fewer.

## 5dx2–y2 orbital electron density

Movie depicting the 5dx2y2 electron density function (ψ5dx2y2)2. The x-axis lies from left to right and the y-axis into the screen away from you.

The 5dx2y2 orbital orbital is related to the 5dxy orbital (below) by a 45° rotation about the z-axis.

## 5dxy, 5dxz, and 5dyz orbital electron density

Movie depicting the 5dxy electron density function (ψ5dxy)2. The x-axis lies from left to right and the y-axis into the screen away from you. The graph on the left shows values of (ψ5dxy)2 on the xy plane drawn through the nucleus while the graph on the right is a plot of values along a single line along the x=y line drawn through the nucleus. The form of the plots for the 5dxz and 5dyz orbitals is similar, differing only in orientation.

Each of the 5dx2y2, 5dxy, 5dxz, and 5dyz orbitals have two planar nodes normal to the axis of the orbital. These orbitals have one spherical node. The higher d-orbitals ( 6d, and 7d) have further spherical nodes while lower d-orbitals (3d and 4d) have fewer.
