Each orbit or shell has a fixed energy and these circular orbits are known as orbital shells. WebEven Dalton's critics were impressed by the power and simplicity of his explanation, and it persuaded many of them that his atomic theory was worthy of further investigation. Unfortunately, Dalton included an additional postulate that prevented his theory from being accepted for many years.
