How did bohr change the nuclear model
WebPostulates of Bohr Atomic Model. Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”. The orbits are termed as “stationary orbit.”. Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not ...
