Choose the element that matches the electron configuration.

Adjust variables to see numerous configurations of the electron orbitals of Benzene.

Electron configurations are a simple way of writing down the locations of all of the electrons in an atom. This article describes how this works.

This article is provided by Florida State University. Schroedinger wave equation is explained and how quantum numbers are used to describe the energy level of any electron in an atom. The relationship of atomic orbitals to quantum...

The website provides an explanation of the electrons' position in their orbitals as they spin around the nucleus. Quantum theory is also explored by explaining that the exact location of a specific electron is a not exact but a guess.

Good look at the orbital hybridization that goes along with the different arrangements of electron clouds. Solid information and graphics.

Cool visual site that shows a 3-D image of the various hybrid orbitals that are possible. Requires the CHIME plug-in to view images.

Very deep presentation of molecular bonding and orbital theory. Nice graphics and text make it a good presentation of some high end material.

Explains the creation of hybrid orbitals and presents their electron density plots and energy diagrams. Requires Java.
