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. For example, NaCl was highlighter yellow, Sr(NO3)2 was sun orange, CuCl2 was turquoise, LiCl was neon red, KCl was solar flare yellow, and BaCl2 was Voldemort green.
Introduction-
In Bohr’s model of the atom, electrons travel around the nucleus in an orbit. The concentric circles in his model represent the energy levels. Electrons can jump from energy level to energy level and absorb or emit light energy when they jump from …show more content…
Seven wooden splints that were soaked in distilled water were then placed into a 250 ml beaker half-full with deionized water to continue soaking. Six weighing dishes were then labeled “NaCl”, “Sr(NO3)2”, “CuCl2”, “LiCl”, ” KCl”, and “BaCl2” were obtained. Each contained a scoop full of each metallic solid in the corresponding weighing dish. After this, the Bunsen burner was carefully lit. The soaked end of one of the metallic splints was then dipped in one of the metallic salts. The “dipped” wooden splint was then placed into the flame and the color was observed. If any of the solid fell on the lab bench or Bunsen burner the test had to be repeated with the same splint and salt. The wooden splint was then immersed in the “rinse water” to fully extinguish it, as well as the match. The splint and match were thrown in the trash after this. The observations for the flame color produced by the metallic salt were recorded in the data table. The previous steps were repeated for the other metallic steps and the observations for the flame color produced by each metallic salt were also recorded in the data table. After the lab was finished, the area was cleaned up, everything was put away, and hands were washed before
