Niels Bohr's Revolutionary Atomic Model

Niels Bohr's atomic model, proposed in 1913, transformed the understanding of atomic structure by introducing the concept of quantized electron orbits. He depicted the atom as a mini-solar system, with electrons orbiting a positively charged nucleus in fixed paths without losing energy. This approach addressed the longstanding question of why electrons do not crash into the nucleus and provided an explanation for the distinct spectral lines observed in hydrogen. Bohr's model established a direct link between the energy levels of electrons and the frequencies of light emitted or absorbed, which significantly advanced the field of quantum mechanics and challenged classical physics.
