Flame tests chemguide
WebA common test to distinguish group 1 and group 2 ions is the flame test, where the metal compound or its solution is heated in a roaring blue Bunsen flame. The resulting coloured flame can be used to identify the cation present. A number of experimental techniques can be used as shown in the videos below. WebFlame Test. Similar to the emission spectrum, elements, when burned also give off light. Elements give off signature colors, and can be used to help ID elements . Objective. Identify the unknown element using the spectroscopes. It is one of the other 5 you are observing!

Atomic emission spectra are created when atoms of an element have energy added to them (by heating, or running electric current through an emission tube filled with a gas). With the naked eye, you see a single color of light (which is the sum total of all the colors of light produced by a given element).
