Rutherford and Bohr describe atomic structure - PBS
WebBohr’s model accounts for the stability of atoms because the electron cannot lose more energy than it has in the smallest orbit, the one with n = 1. The model also explains the Balmer formula for the spectral lines of … Web16 de set. de 2024 · In 1913, the Danish physicist Niels Bohr proposed a model of the electron cloud of an atom in which electrons orbit the nucleus and were able to produce atomic spectra.

Atom - Bohr’s shell model Britannica
Web15 de nov. de 2024 · Bohr model is a modification of the Rutherford model. This model was proposed based on the line spectra of the hydrogen atom. This model proposed that electrons are always traveling in specific shells or orbits around the nucleus. Bohr model also indicated that these shells have different energies and are spherical in shape. WebHow did Bohr expand on Rutherford's model of the atom? He proposed that electrons orbit in fixed orbits with certain sizes and energies. Compare the energy of an electron in the ground state and an electron in the excited state. In an excited state the electron moves up the electron shell from its ground state.
