The flame test lab was an experiment designed to show how elements react when heated this lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element this test showed that there is a direct coloration between the heat energy being expelled. Transcript of chemistry lab - flame tests flame tests - atomic emission and electron energy levels an element has a specific color flame to it which differentiates it from other elements the experiment works with standouts chloride, lead nitrate, cupric chloride, calcium chloride, potassium. (flame test lab) today(-ish) in chemistry, the class performed a very interesting lab it was actually pretty cool, because it involved slight risk if you weren't careful it's better than counting beans, i suppose anyway, the lab that we did was called the flame test lab, and as its name states.

Some common lab techniques massing solids: when obtaining the mass of solid chemicals, always use some type of weighing paper to protect the pan one way to identify elements is by performing a simple flame test in the laboratory when the electrons are heated, they get excited and jump away. The flame test experiment is often used to teach about electronic structure the colors emitted during the experiment are caused by the absorption and release of energy by electrons when a metal ion is heated, its valence electrons absorb energy and move to a higher energy level.
