Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Atomic emission spectrum — The atomic emission spectrum of an element is the set of frequencies of the electromagnetic waves emitted by atoms of that element. Each atom s atomic emission spectrum is unique and can be used to determine if that element is part of an unknown… … Wikipedia
emission spectrum — /əˈmɪʃən spɛktrəm/ (say uh mishuhn spektruhm) noun the spectrum observed when light or other electromagnetic radiation passing through a gas excited in a flame is examined with a spectroscope …

Emission spectroscopy — is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according… … Wikipedia
Emission — may refer to: * Flue gas, also: ** Exhaust gas, flue gas occurring as a result of the combustion of a fuel * Emission of air pollutants * Emission (electromagnetic radiation), the process by which the energy of a photon is released by another… … Wikipedia
Flame test — A flame test is a procedure used in chemistry to detect the presence of certain metal ions, based on each element s characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color.The test involves… … Wikipedia
Flame — A flame is often defined as the visible (light emitting) part of a fire. Physically, it is caused by a highly exothermic reaction (for example, combustion, a self sustaining oxidation reaction) taking place in a thin zone. A flame generally emits … Wikipedia
flame photometer — noun : a spectrophotometer in which a spray of metallic salts in solution is vaporized in a very hot flame and subjected to quantitative analysis by measuring the intensities of the spectrum lines of the metals present • flame photometric… … Useful english dictionary
Atomic emission spectroscopy — (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample. The wavelength of the atomic spectral line gives… … Wikipedia
