Unformatted text preview: 590 KCl Blue and purple 450 CaCl 2 Orange 620 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 4. Potassium is already done as an example for you. Hint : The periodic table is very helpful and can be used as a guide. 3.Identify the color emitted by each of the salts along with the corresponding approximate wavelength using Table 2 in the Introduction. Record your results in Table 5.4. Why does a salt compound give off light (or a colored flame) when burned? During the process of moving from a higher wavelength to a lower one the electrons glue of electromagnetic energy which becomes visible to us. 5.Barium chloride (BaCl 2 ) emits a green color when flame-tested. What can be said about the wavelength of light it emits? The wavelength of the green light can be described as a range from 520-560 ©eScience Labs, LLC 2015 Electron Configuration...
