Jeremy c. zodinliana Asked a Question October 7, 2021 11:08 am 30 pts Answer any FOUR questions from this Part (Each question carry 3 Marks) 1. For a particular atomic state Pin. what are the different possible orientation of inner angular momentum in space (angle betrween inner angul ar momentum and vertical axis)? 2 Find the maximum number of electrons with all the shells fill upto principal quantum number n=3. Show that all the electrons have distinct quantumnumbers when placed in SuOng mgnetuc Tield. 3. The term of a particular atomic state is "Da What are the values of L, S, J? What is the minimum number of electrons which would give rise to this state? How did Sodium D lines split when atom is subjected to low magnetic field? Draw energy level diagram showing t and o sigma components and calculate the possible values of mg 5. A spectral line due to transition from an electronic state P to S state split into three Zeeman lines in the presence of strong magnetic field. Show with diagram that at low magnetic field the number of field/transition lines due to transition to the ground state results in ten lines. 6. 1llustrate with diagrams the splitting of D level of Sodium in weak and strong magnetic field.
