What are the key features of the Bohr model?

What are the key features of the Bohr model?

The Bohr model describes the atom as having a nucleus surrounded by electrons in specific orbits. Key features include quantized energy levels, the idea that electrons can jump between these levels, and the emission or absorption of light when they do.

How does the Bohr model differ from earlier atomic models?

Unlike earlier models, the Bohr model introduced quantization of electron orbits, which explained atomic stability and spectral lines.

What are the limitations of the Bohr model?

The Bohr model doesn't accurately predict the behavior of multi-electron atoms and fails to explain finer details of atomic spectra.

Can you explain the concept of quantized energy levels?

Quantized energy levels mean that electrons can only exist in specific energy states, not in between, leading to discrete spectral lines.

What replaced the Bohr model in modern physics?

The quantum mechanical model of the atom replaced the Bohr model, providing a more comprehensive understanding of electron behavior.
