Bohr's Atomic Model
Manocha Academy・2 minutes read
Niels Bohr proposed the Bohr atomic model where electrons move in fixed orbits around the nucleus, explaining atom stability and line spectra. His postulates included fixed orbits with fixed energy and a quantization condition for angular momentum.
Insights
- Niels Bohr proposed the Bohr atomic model, where electrons orbit in fixed paths around the nucleus, addressing the stability of atoms and line spectra observations, unlike previous models.
- Bohr's model introduced the concept of quantization of energy levels, explaining how electrons can only accept or release specific amounts of energy during transitions between orbits.
- The Bohr model's key postulates include fixed circular orbits with fixed energy for electrons, and the quantization condition that restricts electrons to specific orbits based on their angular momentum, impacting the frequency of radiation absorbed or emitted during transitions.
