Final answer:
Bohr's atomic model differed from Rutherford's by introducing quantized orbits for electrons, explaining the distinctive emission spectra of atoms, particularly hydrogen.
Step-by-step explanation:
Bohr's atomic model differed from Rutherford's because it explained the specific wavelengths of light that atoms emit. Rutherford's model, which depicted electrons circling the nucleus in a planetary fashion, could not account for the unique atomic spectra observed. In contrast, Niels Bohr introduced the idea that electrons can only inhabit certain quantized orbits with specific energy levels. These orbits correspond to distinct energy levels around the nucleus, and transitions between these orbits result in the emission or absorption of light at characteristic frequencies. Bohr's model successfully explained the observed spectra of hydrogen, marking a significant advancement in quantum mechanics.
