The atomic model proposed by Ernest Rutherford marked a significant turning point in the understanding of atomic structure. Before Rutherford’s work, scientists relied on earlier models, such as J.J. Thomson’s plum pudding model, which envisioned the atom as a uniform positively charged sphere with electrons embedded throughout. Rutherford’s experiments, however, revealed that this model could … Read more
