1 markThe diagram shows some of the energy levels of a hydrogen atom.
An excited electron in the level –0.54 eV drops to the level –13.60 eV, resulting in the release of at least one photon.
Which of the following photon energy values could not be produced from this electron transition?
0.31 eV
0.54 eV
12.09 eV
13.06 eV
