Me: So after Dalton's solid atom and Thomson's discovery of electrons, it was Rutherford's Gold Foil Experiment. What did he discover?
Student: He found that the atom was mostly empty space and that there was a positive nucleus and then Bohr said there were electron orbitals.
Me: Fixed orbitals, but yes.
Student: But that is wrong.
Me: Yes, we now know it is an electron cloud.
Student: Dalton's model is the lamest.
Me: . . .
Student: All he said is that things are made up of tiny invisible dots. Thanks a lot Dalton.
