Question

which of the following did scientists learn from rutherfords gold foil experiment? a electrons circle the nucleus in concentric orbitals. b atoms combine in simple ratios to form compounds. c the electron exists and has a negative charge. d the mass and positive charge of the atom are concentrated in the nucleus.

Explanation:

Rutherford's Gold Foil Experiment showed that most of the alpha - particles passed straight through the gold foil, but some were deflected at large angles. This indicated that the mass and positive charge of the atom are concentrated in a small, dense nucleus. Option A is related to Bohr's model, option B is about Dalton's atomic theory, and option C was known before Rutherford's experiment.

Answer:

D. The mass and positive charge of the atom are concentrated in the nucleus
