Ernest Rutherford made a significant contribution to the model of the atom by identifying the nucleus. In his famous gold foil experiment conducted in 1911, Rutherford demonstrated that atoms consist of a small, dense positively charged nucleus surrounded by electrons. This was a pivotal shift from the previous plum pudding model proposed by J.J. Thomson, leading to the modern understanding of atomic structure. Therefore, the correct response is **the nucleus**.
