Bohr's model of the atom is a proposed explanation for the behavior of electrons in atoms, which was proposed by Niels Bohr in 1913. The model suggests that electrons in atoms occupy specific energy levels, or orbitals, around the nucleus. The energy of an electron in an orbital is determined by its distance from the nucleus. According to the model, when an electron moves from one energy level to another, it must either gain or lose energy in the form of a photon. This model was a major step forward in the development of the modern understanding of atomic structure and the behavior of electrons in atoms.
