All of the negative charge was held in the electrons, which must orbit the dense nucleus like planets around the sun. In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't ...

Bohr's model of an atom stated that electrons move in fixed orbitals and that each orbit has a fixed energy. As per NCERT, ‘it was based on the postulate that only certain special orbits known ...

The New Zealander had discovered the atomic nucleus in 1911 and further investigations by Bohr led to his quantum model of the atom where electrons travel around the nucleus in certain orbits. When ...

Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.
