a.

Loses Gains ni = 6; nf = 4

Loses Gains ni = 4; nf = 2

Loses Gains ni = 5; nf = 3

Loses Gains ni = 2; nf = 5

Loses Gains ni = 5; nf = 7

b. Find the transition where the atom gains the most energy. How much energy does the atom gain?

c. Find the transition which will emit the shortest wavelength photon. What is the energy of the photon of this transition

**drwls**, Sunday, April 13, 2008 at 7:42am1) The atom gains energy if nf > ni

"i" signifies "initial" and "f" signified "final".

2) For a hydrogenic one-electron aton, the atom gains the most energy when

1/ni^2 - 1/nf^2 is largest.

3) To emit a photon, the atom must lose energy. For the shortest wavelength,

1/ni^2 -1/nf^2 is the most negative.

To compute the energy gain use the Rydberg relationship. If you don't know it, check it out at
