Atoms and atomic structure: a ‘similar and different’ activity 16 …

WebA theory of the atom or any other system must predict its energies based on the physics of the system. Figure 30.17 An energy-level diagram plots energy vertically and is useful in visualizing the energy states of a system and the transitions between them. WebThese observed spectral lines are due to the electron making transitions between two energy levels in an atom. The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm. steindorfer apetlon rouge
