The 27 pages that link to Flame test, each with the reason it gives.

• PotassiumRelated: Potassium ions produce a pale violet flame, though sodium emission can mask it.

• Analytical chemistryBroader topic: It exemplifies early elemental identification through observable chemical signals.

• SodiumRelated: Sodium’s strong yellow emission makes it readily detectable in a flame test.

• Alkali metalRelated: Excited electrons in several alkali metals emit distinctive visible colors as they return to lower energy states.

• Ionization energyRelated: Excitation and ionization thresholds help shape the light emitted by heated atoms.

• Electron shellBroader topic: Its visible colors arise from electronic transitions between atomic states.

• Atomic spectrumBroader topic: Its characteristic colors arise from atomic emission lines blended by the eye.

• Robert BunsenRelated: Bunsen used flame colors as an early clue to the spectra of elements.

• Emission spectrumBroader topic: Flame colors arise from element-specific emission lines.

• Atomic emission spectrumBroader topic: Flame colors arise from visible atomic emission lines excited by heat.

• CationRelated: Cation emission spectra can produce characteristic flame colors used for identification.

• BariumRelated: Barium salts can produce a pale green flame, a classic qualitative clue.

• Qualitative inorganic analysisBroader topic: It offers a direct emission-based test for certain metal ions.

• RubidiumRelated: Excited rubidium atoms emit distinctive spectral lines that can be observed in flame tests.

• SpectroscopeBroader topic: A spectroscope can distinguish emission lines hidden within a flame's overall color.

• Bunsen burnerRelated: A burner supplies the flame used to excite atoms in the sample.

• Manganese(II)Related: Manganese compounds can produce a characteristic yellow-green flame, though the test is not highly sensitive.

• Copper(II) chlorideRelated: Copper compounds, including CuCl₂, can produce blue-green flame coloration.

• Paul Émile Lecoq de BoisbaudranRelated: Flame observations were among the early clues that led him to investigate gallium.

• Copper(II) sulfateRelated: Copper salts can produce a blue-green flame, though this is not specific to sulfate.

• StrontiumRelated: Strontium salts produce a vivid crimson-red flame.

• Barium chlorideRelated: Barium chloride can introduce barium ions into a flame, which produces a green color.

• Qualitative analysisBroader topic: Distinct flame colors provide a visible clue to some metal ions.

• Lycopodium powderCompared with: Unlike element-identification tests, lycopodium demonstrations use the powder itself as fuel.

• Lithium nitrateRelated: Lithium ions produce a crimson flame, though this test does not uniquely identify lithium nitrate.

• Rubidium chlorideRelated: Rubidium compounds can produce a red-violet flame, though the test is not uniquely diagnostic.

• Strontium nitrateRelated: Heating strontium compounds reveals red emission from excited strontium atoms or ions.
