Web3 de jun. de 2024 · 4. A drawback (and a major one) of Rutherford's model was that the electrons, being accelerated charged particles, would gradually spiral into the nucleus and collapse into it. My question is how did Bohr rectify this drawback in his own model. In Bohr's model too, electrons move in a circular path, which means they are accelerated.
