What is true about the orbits allowed for electrons according to Bohr's model?
Understand the Problem
The question is asking about the characteristics and rules governing electron orbits as described by Bohr's model of the atom. It seeks to identify the correct statement out of the provided options regarding the behavior and arrangement of electrons in an atom according to this model.
Answer
Bohr's model states that only specific, quantized orbits are allowed for electrons, with closer orbits requiring less energy.
In Bohr's model, only specific orbits with certain energy levels are allowed for electrons and these orbits are quantized. Electrons closer to the nucleus have orbits that require less energy, and those farther from the nucleus require more energy.
Answer for screen readers
In Bohr's model, only specific orbits with certain energy levels are allowed for electrons and these orbits are quantized. Electrons closer to the nucleus have orbits that require less energy, and those farther from the nucleus require more energy.
More Information
Bohr's model was instrumental in explaining atomic emission spectra and is considered a precursor to more advanced quantum mechanics models.
Tips
A common mistake is to assume electrons can exist at any energy level, but in Bohr's model, they are restricted to specific quantized energy levels.
