Which answer choice best describes why the results of ernest rutherford's gold foil experiment led him to propose the concept of a nucleus? a.) the positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' negative charges were located at the center of each atom. b.) the positively charged alpha particles were deflected less often than expected, which indicated that the gold atoms' negative charges were not evenly distributed throughout each atom. c.) the positively charged alpha particles were deflected less often than expected, which indicated that the gold atoms' positive charges were located around the outside of each atom. d.) the positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' positive charges were not evenly distributed throughout each atom.
