Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. how heavy is a baby elephantWebTo view an electron in its orbit, you must shine a wavelength of light on it that is smaller than the electron's wavelength. This small wavelength of light has a high energy. The electron will absorb that energy. The absorbed energy will change the electron's position.
