What limitations might an atomic model have in properly illustrating the structure of an atom?

Question

An atomic model cannot be used to represent the relative number of each subatomic particle within a specific atom.

An atomic model helps with calculations to reduce uncertainty of the location of the electrons.

An atomic model can only explain what scientists have observed about the atom and may get updated as new discoveries are made.

An atomic model cannot be a visual representation to help scientists understand relative parts and locations of subatomic particles in an atom.
