Atoms and LightStreaming Video - 2014
Identification of electrons, protons, and neutrons led to a modern subatomic theory. The study of atomic spectra-the light given off by atoms at definite wavelengths-led to the Bohr atomic model, where electrons at distinct energy levels move between these levels by absorbing and emitting discrete quanta of energy. The measurement of atomic spectra has applications in astrophysics as well as forensic chemistry.
