For ideas, check out:

http://metric.ma.ic.ac.uk/chem/

under "Lab 3". It depends how smooth you want the spheres
to appear - because Mathematica graphics are based on 
postscript, smooth-looking spheres are memory-hungry,
though shouldn't be a problem if your computer is a fairly recent
(>= 233 MHz or so) model.
