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).

WebJul 12, 2024 · Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got. WebThese tests for metal ions are always done in solution and adding either sodium hydroxide solution or ammonia solution. You start with a solution of your compound and then add a few drops of sodium hydroxide solution or ammonia solution. Note what happens. Then go on to add an excess of the solution you are adding.
