Part One (Flame Test):

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
Known Elements Color

Barium Green
Calcium Red
Sodium Yellow
Rubidium Violet/Blue
Potassium Blue
Lithium Magenta

Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.
Unknown substance One is Yellow and Unknown substance two is Blue. They gave off the same hues as sodium and potassium.
Part Two (Spectroscopy):

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.
