Write out the 15 microstates of O in a table and then group them into 3 atomic terms. Which term has the lowest energy? Determine the order in energy of levels in this lowest-energy term. The atomic terms and the lowest-energy term of O are exactly same as those of C. The order in energy of the three atomic terms is: 3p < 'D < 'S However, the order in energy of levels of O is the opposite of that of C. The order of the energy levels of the lowest-energy term ³P is: ³P2 < $P1 < ³Po Write out the 15 microstates of O in a table and then group them into 3 atomic terms. Which term has the lowest energy?
