A flame test is conducted when an element is burned and the flame produces a color different the starting flame color. When the coffee stirrer was put into the flame‚ the element’s atoms (from the solution of the stirrer) left the original level of energy. When the atoms fell back to ground level‚ they released photons in the form of colored flame. Using the flame test‚ unknown compounds can be identified when they are burned since each element has a specific color. (Douma‚ 2008). The color
