Rutherford's model describes an atom as having a small, dense positively charged nucleus at its center, surrounded by negatively charged electrons orbiting around it at various distances.
Bohr's Model: Bohr's model is an improvement over Rutherford's model that suggests electrons occupy specific energy levels or shells around the nucleus.
Nuclear Forces: Nuclear forces are attractive forces that hold protons and neutrons together in the atomic nucleus.
