summarize Rutherford's model of an atom, and explain how he developed this model based on the results of his famous gold-foil experiment.
Rutherford's model is basically how we still view the atom today: a small, positively-charged nucleus with electrons orbiting around, with a whole lot of empty space.As for the gold-foil experiment, he shot positively charged alpha particles through an extremely thin piece of gold. Most went right through the gold foil as most of the atom is space. However, some were reflected at huge angles, because they scored a "direct hit" on the nucleus. Like charges repel, so any of the alpha particles that came close to nuclei inside the gold foil were sent flying at angles.
