1) Electrons exist in stable orbits around a nucleus. Electrons in such an orbit do not emit radiation.
2) If an electron moves from one stable orbit to another, it absorbs or releases radiation with energy corresponding to the energy difference of the orbit.
3) All electrons in stable orbits have quantised angular momentum (their angular momentum can only take certain values).
The rule is 2n sq..if we follow the 2n2 rule, then M shell should have 18 electrons whereas it can possess at the max 8 electrons.
