Which of the following was NOT a conclusion of Rutherford’s gold foil experiment?

A. The atom is mainly empty space
B. The nucleus has a negative charge

D. Alpha particles can pass through a thin sheet of gold foil

xlmichael · Answer

The answer is b.) The nucleus has a negative charge 
 It was not a conclusion because it is neutral. It is not positive nor negative.

xlmichael · Answer

The correct answer is B: The nucleus has a negative charge, as it was not a conclusion from Rutherford's experiment. Rutherford concluded that the atom is mainly empty space, has a dense nucleus with a positive charge, and that alpha particles can pass through gold foil. The nucleus actually has a positive charge due to protons, not a negative charge.
