The
conceptual model provides a concept of how the components of an atom
are arranged, implying a similarity of the forces acting between those
components.
It is important to note that the conceptual model is not necessarily
correct or accurate. It simply provides a model which forms the basis
for the discussion of the concepts involved.
Science is all about the discussion -- with the expressed aim of
improving the conceptual model to the point that it is self-consistent
and consistent with the existing body of accepted knowledge. [The
hardest part is knowing when and how to question the body of accepted
knowledge.]
