Why do electrons emit color in a flame test?
Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab, the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum, which one can use to identify them.
How is a spectroscope used in a flame test?
A spectroscope can be used to see a pattern of narrow lights called an emission (bright-line) spectrum. The actually wavelengths of the spectrum serve as a quantitative test to determine atoms identities. Each element has a different “pattern” of electrons so it will show a different combination of colors.
