Which model of the atom first proposed that electrons orbit the nucleus?
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.
