Question

which statement best supports rutherfords idea that an atoms positive charge is concentrated in a small core at its center? samples of uranium ore emit particles that produce images on photographic film. atoms are neither created nor destroyed in any chemical reaction. alpha particles passing through a thin sheet of gold foil are scattered in all directions. electrical and magnetic fields deflect cathode rays in mathematically predictable ways.

Explanation:

Rutherford's gold - foil experiment involved shooting alpha particles at a thin gold foil. The fact that alpha particles were scattered in all directions when passing through the foil indicates that there is a small, dense, positively - charged nucleus in the atom. The other statements are not related to this idea. The first statement is about radioactivity, the second is about the law of conservation of atoms in chemical reactions, and the fourth is about cathode rays and electromagnetic fields.

Answer:

Alpha particles passing through a thin sheet of gold foil are scattered in all directions.
