which scientist proposed the idea of the nucleus after the unexpected results of his students gold foil experiment?
rutherford
democritus
bohr
dalton

Explanation:

Rutherford's gold - foil experiment led to the discovery of the nucleus. In this experiment, when alpha particles were bombarded on a thin gold foil, most of them passed through, but a few were deflected at large angles. This unexpected result suggested that the atom has a dense, positively charged nucleus at its center. Democritus proposed the concept of atoms as indivisible particles. Bohr proposed a model of the atom with quantized energy levels. Dalton proposed the atomic theory which stated that atoms are the basic units of matter and that elements are composed of identical atoms.

Answer:

Rutherford
