Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted. Web21 de fev. de 2024 · Bohr’s Model Of Atoms. A year after the publication of Rutherford’s atomic theory, Niels Bohr found a discrepancy in the model. If electrons were to orbit around a positively charged center, at some point, those electrons would lose their energy and collapse into the nucleus, making the atoms unstable.
