![]() ![]() The emission spectrum of atomic hydrogen is divided into a number of spectral series, with wavelengths given by the Rydberg formula: \frac. Hydrogen Spectrum: Spectral lines of Hydrogen, divided into series. Similarly, the emission spectra of molecules can be used in chemical analysis of substances. Each element’s emission spectrum is unique, and therefore spectroscopy can be used to identify elements present in matter of unknown composition. The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by an atom’s electrons when they are returned to a lower energy state. emission: In a spectral sense, what occurs when an electron transitions between a higher energy level and a lower one, resulting in the release of a photon of predictable energy.While the model had its limitations, it paved the way for further. (b) The energy of the orbit becomes increasingly less negative with increasing n. Figure 7.3.2: The Bohr Model of the Hydrogen Atom (a) The distance of the orbit from the nucleus increases with increasing n. It successfully explained the emission spectra of hydrogen and hydrogen-like atoms and introduced the concept of quantized energy levels. In this state the radius of the orbit is also infinite. The intensity of spectral lies could not be clarified by Bohr. Bohr’s atomic model made significant contributions to our understanding of atomic structure and the behavior of electrons within atoms. ![]() Orbits were presumed to be circular but Sommerfield further stated that these orbits are elliptical.
