1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame

2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.
Part Two (Spectroscopy):
1. Create and complete a data table for Part Two of the lab. It should include the name of the element, the colors, and the wavelength values of the observed lines.

2. Describe the line spectrum of the star. Give the color and wavelength value of the five brightest lines in the spectrum.
Conclusion:
1. Explain, in your own words, why different elements produce different colors of light when heated.

2. Why do you think elements must be heated before they emit colored light?

3. What element do you think is the most abundant in the star that you observed in Part Two? Explain your answer.

    The flame testing is a method used in chemistry to detect the presence of certain ions, primarily metal ions, based on each element’s characteristics emission spectrum. The colour of the flames normally depends on the temperature. Different types of Bunsen burner with flame types depend on the oxygen supply. The flame of rich fuel with no premixed oxygen produces a yellow diffusion flame. The flame of lean fully oxygen premixed flame produces no soot and the flame colour is produced by molecular radicals, especially in CH and C2 band emission.…
