Atomic orbitals 7d electron "dot-density"

This page shows representations of electron density in two ways. The first is two-dimensional electron "dot-density" diagrams - plots across an appropriate plane of each 7d orbital. These were created using a Monte Carlo computational method. The second allows you interact (zoom, rotate) with three-dimensional electron "dot-density" models representing electron density of the various 7d atomic orbitals created by the same Monte Carlo computational method. Red represents regions for which the wave functions are positive and white represents where values are negative.

7dz2 electron "dot-density"

The first image shows a two-dimensional electron dot-density plot of the 7dz2 orbital (z-axis is vertical). The second image is an interactive (see below for instructions) represention of electron density in three-dimensions for the same orbital. The shapes of the 7dxy, 7dxz, 7dyz, and 7dx2-y2 orbitals differ and shown below.

7dx2y2, 7dxy, 7dxz, and 7dyz orbital electron density

The first image shows a two-dimensional electron dot-density plot of the 7dxy orbital (across the z=0 plane). The 7dxz orbital (across the y=0 plane and 7dyz orbital (across the x=0 plane) are similar in appearance. The 7dx2y2 is identical in appearance but rotated by 45° in the plane of view. The second image is an interactive (see below for instructions) represention of electron density in three-dimensions for the same orbitals.

Using JSmol

You can use your mouse to manipulate the "orbital" in the "JSmol" image above. How you do this depends upon how you are viewing this page but the following may help.

  • On a mobile device experiment using one or two fingers to rotate and zoom
  • On a computer, to rotate about the x and y directions, drag mouse around the image
  • On a computer, to rotate about the z direction (which comes out of the screen towards you), hold shift and drag mouse horizontally
  • To zoom, hold shift key down and drag mouse vertically
  • To reset the image, hold down shift key and double click ony part of the image not containing dots
