Which of the following statements are not true about the Rutherford Planetary Model? Loss of energy by an electron results in a change in position relative to the nucleus. Orbiting electrons are accelerating. Accelerating electrons give off electromagnetic radiation. Electrons increase distance from the nucleus after energy loss. Electrons follow an orbital path.
