Hi. This isn't so much a homework question, but more of a conceptual understanding question.
Lets say an atom has a ground energy level defined at 0J.
The energy levels are:
E1 = 0 J
E2 = 7.77*10^-19 J
E3 = 10.66*10^-19 J
E4 = 14.1*10^-19 J
E5 = 16.6*10^-19 J
Now, if an electron with over 16.6*10^-19 J of energy is shot into the atom, what are the possible energies of photons that can be emitted?
I would have started by saying:
7.77*10^-19 J
10.66*10^-19 J
14.1*10^-19 J
16.6*10^-19 J
my textbook seems to agree with me there. Now, i would also think that more energies are possible, because of electrons going from one energy level other than the ground state to another. So the following would also be possible:
2.89*10^-19 J
6.33*10^-19 J
3.44*10^-19 J
etc...
The book didnt explicitly say these arent correct, but it didnt really mention them, so I am not sure if my understanding is correct or not.
Any help is appreciated,
Thanks in advance,
Dan.
