Since the 1980s, scanning-tunnelling microscopes have been used to image individual atoms. These microscopes detect electrons as they tunnel across the distance … WebAtomic electron transition is a change (or jump) of an electron from one energy level to another within an atom or artificial atom. It appears discontinuous as the electron "jumps" from one quantized energy level to another, typically in a few nanoseconds or less. It is also known as an electronic (de-)excitation or atomic transition or quantum jump. chinese flag colors represent https://qbclasses.com
