1 Schedule for the concerts in Regina is refreshed on a regular basis. 2  Regina is really one of the best areas for concert tours in America.
1 Niels Bohr suggested that electrons in an atom were restricted to specific orbits around the atoms nucleus. 2  Bohr argued that an electron in a given orbit has a constant energy, thus he named these orbits energy level.
The Bohr's Theory. The discoveries of the electron and radioactivity at the end of the 19th century led to different models for the structure of the atom. In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities.Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.n 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities.
