Flame Test Lab
Summary In this lab, students were given many different substances to hold over a flame and were asked to observe the colors of the flame produced. This helped demonstrate the relationships of the flame colors and the certain atoms contained in compounds. Pre-lab Questions 1) What is the difference between ground state and an excited state? Ground state is the most stable state where all the electrons are in the lowest energy levels. On the other hand, an excited state is where the electrons are in an unstable arrangement, and will go back to their normal positions of lower energy. 2) What does the word "emit" mean? The word "emit" means to "produce and discharge", especially in gas or radiation. 3) In this experiment, where are the atoms getting their excess energy from? In this experiment, the atoms are getting their excess energy from the heat of the bunson burner's flame, where the electrons can reach an excited state. 4) Why do ...
