The transitions labelled (A) to (E) in the figure below represent an electron moving between energy levels in a hydrogen atom. Answer the following questions. 1. Which transition represents an electron that gains 10.2 eV of energy? 2. Which transition represents an electron that loses 10.2 eV of energy? 3. Which transition represents an electron that is breaking free of the atom? 4. Which transition, as shown in the figure, is not possible?
