Electrons orbit the nucleus in fixed paths called energy levels or 'shells.' Each shell has a specific energy level that increases with distance from the nucleus. Electrons can move between shells by absorbing or releasing energy as light. The model explains atomic emission spectra (distinct colors emitted when electrons change levels). Limitations include violating the Heisenberg Uncertainty Principle and not fully explaining larger atoms.
Understand the Problem
The question is discussing the concept of electron orbitals and the behavior of electrons in an atom, particularly in relation to energy levels, emission spectra, and the limitations of the atomic model described.
Answer
Electrons move in fixed energy levels, changing levels by absorbing/releasing light energy.
Electrons orbit the nucleus in fixed paths called energy levels or 'shells.' These increase in energy as they get further from the nucleus. Electrons can move between shells by absorbing or releasing energy as light. The Bohr model explains atomic emission spectra but has limitations with the Heisenberg Uncertainty Principle.

Electrons orbit the nucleus in fixed paths called energy levels or 'shells.' These increase in energy as they get further from the nucleus. Electrons can move between shells by absorbing or releasing energy as light. The Bohr model explains atomic emission spectra but has limitations with the Heisenberg Uncertainty Principle.
More Information
The Bohr model revolutionized atomic theory by introducing quantized electron orbits. It successfully explained hydrogen's spectral lines. However, it falls short in accurately describing atoms with more electrons and violates quantum principles.
Tips
Be cautious not to conflate the model's fixed orbits with actual electron behavior, which according to quantum mechanics, is probabilistic rather than deterministic.
