Using bohr's theory, predict the third ionization energy for 'li (in j). (hint: this is similar to the problem of finding the ionization energy of 'li". you can directly quote the results from problem 1 for a nucleus of an atomic number equal to 3 in your solution. however, in this problem, you are required to apply the reduced mass concept and modify your formula from problem 1 by replacing the mass of the electron, me, with the reduced mass of 7i (what is it? )
