develoment of atomic model started from Faraday who gave clue of electron, Crook confirmed the existence of electrons and proton in an atom.
For further confirmation of the presence of electrons and protons that was done by Henry ( discoverer of radioactivity ) . Then Chadwick discovered the presence of neutron. Rutherford said that atom has two parts one is nucleus and other other part is extra nuclear region. Bohr gave the true picture of atom by showing the atomic model of hydrogen .
More than hundred other scientists worked with them as coworkers, definitely their contribution cannot be forgotten.The first person to develop the first model of the atom in 1803 was John Dalton Atomic models developed proper formulas of the compounds, and proportions of the atoms.

Answer: Experiments

Explanation:

Models of the atom are developed by experiments in which evidences that support various models are obtained via ingenious means. For instance, in Rutherford's experiments, he made use of a thin gold foil. The foil contains gold atoms though they cannot be seen with naked eyes. The inferences deduced from the experiments can be generalized to all atoms since atoms of all elements posses essentially the same structure even though the energy levels are different for each atom.
