http://en.wikipedia.org/wiki/Space-filling_model

So since in a space filling model each atom is represented by a sphere, you mainly need to look at the number of atoms in the molecule, and also at their relative size.

H2, diatomic hydrogen, has two atoms of the same size (2 Hydrogen atoms), so would be to equal size spheres kinda squashed together
