Recently, Crusaders took to the chemistry lab to participate in the annual Flame Test experiment. “The lab illustrates when electrons are brought to the “excited” state (energy given in the form of heat from the flame) they must release energy. This energy is released in the form of light (colors),”said Mr. Peter Valiente ’79, Department Chair.
This lab also reinforced how electrons release energy in the form of light seen in the visible spectrum. These lights, however, could be invisible, infrared, or ultraviolet radiation. Crusaders also learned that metals give off specific colors which help scientists identify them. “It is a more hands-on activity to see the properties of ions with different elements,” commented Nick Gendron ’19. For example, they witnessed and learned that sodium gives off a bright yellowish orange flame, and that potassium releases a purplish color. Students also were intrigued to learn what role these elements play in activities such as fireworks.
