Which feature was missing from John Dalton’s, J.J. Thomson’s, and Ernest Rutherford’s models of the atom, and why was this missing feature a disadvantage?

The charge of electrons was not included in these models. This was a disadvantage because the results from experiments involving cathode-tube rays could not be explained.

The behavior of electrons was not included in these models. This was a disadvantage because properties of bulk materials, such as metals, could not be explained.

The location of protons was not included in these models. This was a disadvantage because experimental results from the gold foil experiment could not be explained.

The location of electrons was not included in these models. This was a disadvantage because experimental results involving light and blackbody radiation could not be explained.
