What are the main differences between what the space filling model and the ball and stick model each show most clearly?

The difference between them is that instead of sticks representing bonds, as in the ball and stick model, the spheres that represent atoms are fused together and the size of the sphere represents the size of the actual atom.

Explanation:

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
