List the steps involved in russell-saunders (l-s) coupling to obtain states arising from an electronic configuration. write out the formulae involved and explain the meaning of any symbols used. (10) given that the lowest energy transition of atomic magnesium ([ne]3s? ) involves the promotion of an electron from the 3s atomic orbital to the 3p orbital: (1) obtain the states arising for both configurations, (ne]3s2 and [ne]3s3p. [10 m (ii) order the states derived in part (i) from the lowest to highest energy. (5 md (ii) from your answer in part (ii), determine the lowest energy allowed absorption transition of magnesium. justify your answer.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
