Of the following transitions in the Bohr hydrogen atom, the ____ transition results in the emission of the highest-energy photon.

a.n=1, n=6
b.n=6, n=1
c.n=6,n=3
d.n=3,n=6
e.n=1,n=4

The most energy comes from the largest "movement" of the electron; therefore, I would think that would be from 6 to 1.
B: n=6, n=1 is highest-energy photon. Emission is going from a higher energy level down to a lower energy level, so that will rule out a,d,e. So between b and c, it will be b because if you study the n=1 energy level you will see that it is the ground state energy level, which means that energy is the greatest in this energy level.
