J.J. Thomson's experiments supported the existence of a particle that deflected away from a negative charge and toward a positive charge. Ernest Rutherford found that when positive particles were fired at gold foil, some of the particles deflected rather than passing straight through. Taken together, these experiments support our understanding of the

A) flavors of quarks.

B)structures of the atom.

C)specific gravity of gold.

D)law of conservation of energy.

is it D?

The answer is B

Since when is this biology?

Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.

No, the correct answer is B) structures of the atom. J.J. Thomson's experiments with cathode rays led to the discovery of electrons and supported the existence of negatively charged particles in an atom. Ernest Rutherford's experiments with gold foil and alpha particles revealed that atoms have a dense, positively charged nucleus, with most of the atom being empty space. This led to the development of the nuclear model of the atom and contributed to our understanding of the structures of atoms. The other options, A) flavors of quarks, C) specific gravity of gold, and D) law of conservation of energy, are not directly related to the experiments conducted by Thomson and Rutherford.
