Post-Lab Questions

1. Write out the electron configurations of carbon and each of the metals of the salt compounds used. Record this in Table 3. Potassium is already done as an example for you. Hint: The periodic table is very helpful and can be used as a guide.4

2. Identify the color emitted by each of the salts along with the corresponding approximate wavelength using Table 1 in the Introduction. Record your results in Table 4.

3. Why does a salt compound give off light (or a colored flame) when burned?

4. Barium chloride (BaCl2) emits a green color when flame-tested. What can be said about the wavelength of light it emits?

ESSAY GUIDELINES -:

Write a 1000-1500-word essay addressing each of the following points. Be sure to completely answer all the questions for each bullet point. There should be two main sections, one for each bullet below. Separate each section in your paper with a clear heading that allows your professor to know which bullet you are addressing in that section of your paper.

Support your ideas with at least three (3) sources using citations in your essay. Make sure to cite using the APA writing style for the essay. The cover page and reference page in correct APA do not count towards the minimum word amount. Review the rubric criteria for this assignment.

Length: 1000-1500 words; answers must thoroughly address the prompts in a clear, concise manner.
