[Demo] Colored Flames - light | Coursera
Each flame needs time to get extremely hot to yield the maximum emission from the metal. On the camera, this sodium burning looks kind of pink, but in real life, it was quite yellow. Since you have plenty of sodium chloride at home, you can check this one out live, but make sure you have a controlled environment for containing the flame.

Discover the Flaming Colors of Fireworks | STEM Activity
The color, or colors, that a firework makes depends on what color-producing chemicals are in the firework. These chemicals are various metal salts that burn when the firework goes off, and burning the metals is what makes the colors. Different metals give off
Lab: Flame Test Flashcards | Quizlet
When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame. Some metals and the colors they produce are: barium, yellow-green; calcium, red-orange; copper salts (except halides), emerald green; copper halides or other copper salts moistened with hydrochloric acid, blue-green; lithium, crimson; potassium, violet; sodium, yellow

Chemistry The Flame Test Name
A flame test is a qualitative analytic procedure used to detect the presence of certain elements, primarily metal ions, based on the emission spectrum. The test involves introducing a sample of the element or compound to a hot, non-luminous flame, andthe color
Flame test - Many of the alkali and alkaline earth metal salts give colored flame tests that are characteristic of the metal ion present. Take a small amount of the salt on the nicrome wire as directed by your instructor and test it in the Bunsen burner flame.
What gives fireworks their different colors? - Quora
When chemicals present in the fireworks composition get heated, the ions emit characteristic wavelengths or colors of light. This works much like the flame test a method used to identify a substance by its color in a flame. Metal ions are responsi
Classroom Resources | Flame Test (Rainbow Demo) | AACT
Strontium Chloride: red or crimson flame Students should record the color on their activity sheets and use the visible light spectrum chart to estimate the wavelength or frequency of each. Put a strontium and a copper splint into the flame at the same time and ask students to identify which metals are present.
2 Why does each metal produce a different color …
2) Why does each metal produce a different color? Different elements have different flame colors because their electrons have different allowed energy levels. When the atom is heated, some electrons are excited to a higher level. When an electron drops from one
Flame Test- Strontium Chloride -
The flame test is preformed by burning a metal salt using a flammable liquid. Each chemical (in this case metal ion) gives off a characteristic color (seen here as changes in colors of the flames) when the electrons fall back down from their excited state and emit light at certain wavelengths (colors).
Lab #7: Observing the Behavior of Electrons Background
Lab #7: Observing the Behavior of Electrons Background: By placing atoms of a metal into a flame, electrons can be induced to absorb energy and jump to an "excited energy state" - a quantum leap. They then return to their ground state by emitting a photon of
