MU - Chemistry 210
IAE on Atomic Orbitals
The place to start this adventure is Brucat's web site of
Atomic Orbitals at the University of Florida.
Check out the AOs for main quantum numbers n = 1 - 3.
Notice the spherical nodes in the s-AOs with
n>1. Look at the p-AOs 2p and 3p. Both have a node plane (they are p-AOs
and l=1) and 3p also has a node sphere in addition! Check out the set of
five d-AOs. They come in different shapes. Can you draw them?
of Orbitals illustrates well the spherical nodes in ns-AOs (n=1-3).
NOTE that the electron density is plotted for the ns-AOs. Any
idea what the actual orbital function would look like?
I also found a site where you can download a Mathematica program that
allows you to draw
representations of atomic
orbitals. If you are a Mathematica enthusiast, you
might try that out. Otherwise skip it.
Models of Atomic Orbitals. This site requires a VRML plug-in and a
lot of memory. Since these virtual reality presentations, you can rotate
and translate the MOs at will. Quite good!
Let me know if you can find other sites on the web that help learning
about atomic orbitals, molecular orbitals, hybridization and bonding. If
you bring a site and it get's posted, I will acknowledge you by name.
