Only the molecules included in General Chemistry by Brady and Humiston 4ed. were rendered. Stills of each animated GIF file are shown. Atomic Orbitals The electron orbitals presented represent a volume of space within which an electron would have a certain probability of being based on particular energy states and atoms. The shape of the orbital depends on many factors. The most important are the quantum numbers associated with the particular energy state. These are n, the principal quantum number, l, the oribital quantum number, and m, the angular momentum quantum number. The following table shows some of these shapes. Atomic Orbitals The orbitals can be viewed in any order. Using your mouse allows each orbital to rotate. An atomic orbital multiple choice test is also included complete with animation. CAChe: An Online Molecular Modeling Tutorial CAChe is an extremely powerful tool used in building molecules. CAChe - Molecular Modeling Tutorial CAChe is an extremely powerful tool used in building molecules. This tutorial will guide you through the basics in building molecular structures.
