what does john dalton's billiard ball model show us

Apr 02, 2011 · That is basically it. John Dalton's model represents an atom as a solid ball of matter with no moving parts. His model only shows that atoms of the same element have the same masses (same size billiard balls), atoms of different elements have different masses (different size billiard balls), and that atoms of different elements combine in definite proportions to form compounds.
