all made up of the same basic elemental components (quantized mono-charges)all components are bound together by electro-static attraction forcesall have internal repel electro-static forces that are less than the attraction forces
Differences
distance between charges creating the net binding forces, larger distance means weaker binding forcesnumber of basic elemental components (mono-charges), ie just more of the same components. Seen as differences in mass, weight, inertia.
