**Solution:** Bohr's orbits are referred to as stationary states for several reasons: 1. **Fixed Energy Levels**: In Bohr's model, electrons in these orbits possess specific, quantized energy levels. This means that each orbit corresponds to a certain energy state, and the electron does not lose energy while in that orbit. The energy levels are discrete, and the electron can only exist in these defined states. 2. **Fixed Radii**: The orbits themselves have fixed radii. Each energy level corresponds to a specific radius from the nucleus. As the electron moves to a higher energy level, it occupies a larger orbit, but within each energy level, the radius remains constant. ...
