WebTo 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. We can never know both the momentum and position of an electron in an atom.
