Bohr Model

The Bohr Model describes the atom as a small, dense nucleus surrounded by electrons that travel in specific, fixed orbits or energy levels. Electrons occupy these levels without spiraling into the nucleus. When an electron moves between levels, it absorbs or emits a precise amount of energy, often as light. This model helps explain atomic stability and the distinct spectral lines observed in elements. While it simplifies the complex behavior of electrons, it was a key step in understanding atomic structure and laid the groundwork for modern quantum mechanics.
