In the gold foil experiment, Ernest Rutherford discovered the presence of a small, dense, positively charged nucleus at the center of the atom. This experiment demonstrated that atoms consist of a central nucleus surrounded by electrons, contradicting the earlier plum pudding model of atomic structure. Therefore, the correct answer is:
**The presence of a small, dense, positively charged nucleus.**
**The presence of a small, dense, positively charged nucleus.**
