Niels Bohr was a Danish physicist born in 1885, renowned for his groundbreaking contributions to understanding atomic structure and quantum theory. He developed the Bohr model of the atom in 1913, introducing the concept of quantised energy levels for electrons, which helped explain atomic stability and spectral lines. His work laid the foundation for modern quantum mechanics, earning him the Nobel Prize in Physics in 1922.
He proposed that electrons move in fixed energy levels, or "shells," without losing energy, preventing them from spiralling into the nucleus. This explained the stability of most atoms and accounted for the specific energy emitted or absorbed by electrons, solving key issues in Rutherford’s model.
