10.3: Emission Spectra – Chemistry LibreTexts
The emission spectrum (or line spectrum) of a chemical element is the unique pattern of light obtained when the element is subjected to heat or electricity. When hydrogen gas is placed into a tube and electric current passed through it, the color of emitted light is pink. However, when separated using a prism or diffraction grating, the …https://socratic.org/questions/how-can-atomic-spectra-be-used-to-identify-elementshttps://socratic.org/questions/how-can-atomic-spectra-be-used-to-identify-elements
How can atomic spectra be used to identify elements? – Socratic
Answer link Each element has its own unique atomic emission spectrum. You can look at the spectra and identify which elements are present. When an atom absorbs energy, its electrons jump to higher energy levels. Then they jump back down again. Each jump corresponds to a particular wavelength of light.https://chem.libretexts.org / Courses / City_College_of_San_Francisco / Chemistry_101A / Topic_E:_Atomic_Structure / 07:_Electronic_Structure_of_Atoms / 7.03:_Line_Spectra_and_the_Bohr_Modelhttps://chem.libretexts.org / Courses / City_College_of_San_Francisco / Chemistry_101A / Topic_E:_Atomic_Structure / 07:_Electronic_Structure_of_Atoms / 7.03:_Line_Spectra_and_the_Bohr_Model

In fact, Bohr’s model worked only for species that contained just one electron: H, He +, Li 2 +, and so forth. Scientists needed a fundamental change in their way of thinking about the electronic structure of atoms to advance beyond the Bohr model.

Atoms and Electromagnetic Spectra – Chemistry | Socratic
Each transition has a specific energy difference. This collection of transitions makes up an emission spectrum. These emission spectra are as distinctive to each element as fingerprints are to people. Thus, scientists can use atomic spectra to identify the elements in them. You can view the atomic spectrum of each athttps://www.khanacademy.org/science/hs-chemistry/x2613d8165d88df5e:atoms-elements-and-the-periodic-table/x2613d8165d88df5e:the-bohr-model-and-atomic-spectra/a/absorptionemission-lineshttps://www.khanacademy.org/science/hs-chemistry/x2613d8165d88df5e:atoms-elements-and-the-periodic-table/x2613d8165d88df5e:the-bohr-model-and-atomic-spectra/a/absorptionemission-lines
Absorption spectrum (emission spectrum lines) (article) – Khan Academy
Emission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. When light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands.https://www.khanacademy.org/science/chemistry/electronic-structure-of-atoms/bohr-model-hydrogen/a/spectroscopy-interaction-of-light-and-matterhttps://www.khanacademy.org/science/chemistry/electronic-structure-of-atoms/bohr-model-hydrogen/a/spectroscopy-interaction-of-light-and-matter

The energy transitions for the electrons of each element are unique, and are distinct from one another. Thus, by examining the colors of light emitted by a particular atom, we can identify that element based upon its emission spectrum.
