Bunsen Burner with striker. What feature(s) would you expect from the atomic spectra of potassium? Explain your reasoning. These labs are responsible for conducting tests that meet the standards set by A glowing splint bursts into flames when exposed to an oxygen-rich environment because the abundance of oxygen accelerates the combustion reaction of the splint material. In experiment 9, page 7 showed the atomic spectra of calcium and sodium. Chemists can identify these elements with a flame test (see figure 1). Atomic Line Spectrum Safety: Do not touch the lights in the discharge tubes they are very hot! 1. You have just returned from the moon with a handful of crystals. A fluorescent light bulb contains hot gaseous mercury Atomic Emission Spectra Lab Updated. The lab encourages understanding of how an element's electron configuration leads to specific light colors when heated, and how star age can be inferred through its elemental composition.
