Consider these two cases.
Case 1 An electron jumps from energy level 1 to energy level 3 in an atom.
Case 2: An electron jumps from energy level 1 to energy level 4 in an atom.
For case 1, what happens when an electron jumps from energy level 1 to energy level 3 in an atom?
1. A photon is absorbed by the atom.
2. A photon is emitted by the atom.
3. A proton is absorbed by the atom.
4. A proton is emitted by the atom.
Assuming that both cases describe Hydrogen-like atoms with one electron, for which case is more energy emitted or absorbed?
1. The energy is the same for both cases.
2. More energy is emitted or absorbed for case 2
3. It is impossible to tell.
4. More energy is emitted or absorbed for case 1
