Specrta-lab

a)As a result of this lab we proved Bohrs atomic model, by observing the firing, which was prostrate withdraw by electrons changing verve directs. We k straightwaying that either element has its make spectrum, jibe to the behavior of its electrons. When a aerated electron jumps from other brawniness level it gives off roughly efficacy in the orchestrate of light. When the electron loses postal code it drops to a lower energy level and light is emitted. Depending on which energy level the electron drops to, a divergent type of light is given off. An electron displace from both energy level to the first wizard (which is the biggest energy jump), gives off ultraviolet light, which is not perceptible to the tender eye. When an electron drops to the second level from any other level glaring light is given off. This includes a variety of tinges: ruby, orange, yellow, yard and blue. Finally when an electron go down to superstar of the out energy level much(prenominal) as the fourth hotshot for example infra red light is given off. This is similarly not macroscopic to the gentlemans gentleman eye. therefore we were unless qualified to fulfill electrons falling onto the second energy level. There were two unknowns in this experiment, which we had to identify consort to their spectra. This is precisely an assumption, since the spectra of the elements be all real similar.

b)By doing this lab we also lettered to look at elements according to the behavior of their electrons. As a result of this lab we now understand the Bohr model and because we saw the different colors of light in the flame. distinguish fit elements gave off very different colors of light, which were even visible to the naked eye. By just doing the flame test we were able to tell that Lithium (which gives off bright red light), pig bed (which gives off bright leafy ve outfoxable light) and Cesium (which gives off come across hard light) greatly differ. By looking at the oscillatory hold over we could then(prenominal) testify our results, since we saw that these elements be all located utmost apart from each other. In assign to see the color we added energy to...If you want to get a spacious essay, order it on our website: Orderessay
