Which of the following is a correct statement about the Rutherford scattering experiment?
A)The experiment provided an explanation of the discrete lines in atomic spectra
B)The experiment yielded evidence that electrons are charged particles but neutrons are not electrically charged
C)The experiment showed that the electrons contain nearly all of the mass of the atom
D)The experiment provided evidence that matter does not consist of atoms
E)The experiment indicated that at the center of the atom is a tiny and extremely dense nucleus

The Rutherford scattering experiment involved firing alpha particles at a thin gold foil, and observing the scattering pattern. The experiment indicated that a few alpha particles were scattered at large angles, which indicated that they had interacted with a very small, positively charged nucleus at the center of the atom. This provided evidence for the concept of a small, dense atomic nucleus and led to the development of the modern model of the atom. Choice A is incorrect because atomic spectra were explained by other experiments, such as the Bohr model of the atom. Choice B is incorrect because the experiment did not involve neutrons. Choice C is incorrect because the experiment found that most of the mass of the atom was concentrated in the nucleus, not the electrons. Choice D is incorrect because the experiment provided evidence for the existence of atoms.
