Quantum Phenomena - discrete energy levels for electronsQ2. Some energy levels of an atom of a gas are shown in diagram 1. Diagram 1 When a current is passed through the gas at low pressure, a line spectrum is produced. Two of these lines, which correspond to transitions from levels B and C respectively to the ground state, are shown in diagram 2. Diagram 2
