Flame Test Lab - Shaun Alba''s DP
When different metal ions are placed into a flame it creates a reaction that causes the electrons to quantum jump and puts them in an excited state. When this happens the electrons emit photons of light to return to the ground state.
Why do different elements burn different colors during a …
2009/3/19· 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
How To Make Green Fire | Science Trends
Calcium will cause flames to burn an orange color, but the color is typically rather muted so it can be difficult to differentiate it from the yellow colors of sodium. Calcium is an alkali metal that occurs naturally in various types of rocks, and calcium compounds are frequently used in food additives, pharmaceuticals, and other products.
