Due after completing the lab. Different elements emit different emission spectra when they are excited because each type of element has a The responding variable was the color of the flame. It can be in the form of light, an electric discharge, or heat. When elements are heated to high temperatures, some of their electrons absorb energy. You observed the spectral lines for different elements. Alright, so looking to do this experiment with your students? The reason each of the elements produced a different color (or series of wavelengths) is because of the make up of the atom. When heat is applied to the atoms, some electrons can have high energy levels and fall to the lower levels. 0000003131 00000 n
Unfortunately, techniques more sophisticated than those used in this lab are required to obtain such line spectra. excited electrons in the atoms give off light and fall back to lower shells.

A metal salt is a compound of a metal and a nonmetal. Sodium Flame test. The metals were then in the (ground, excited) state. When dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. Do you think your observation is related to the type of light emission you saw in the lab? For example, sodium makes the flame turn bright orange this is the same orange color made by sodium street lamps and many fireworks. The production of specific photons by specific elements is very useful to astronomers because they can look at the wavelengths of the photons that are produced by stars to determine the elements that compose that star.
