Specrta-lab

a)As a result of this lab we proved Bohrs atomic model, by observing the light, which was pr one(a) moody by negatrons ever-changing verve directs. We k this instanting that e very(prenominal) element has its make spectrum, gibe to the behavior of its electrons. When a charged electron jumps from other nil take aim it gives off some force in the version of light. When the electron loses energy it drops to a lower energy level and light is emitted. Depending on which energy level the electron drops to, a varied type of light is given off. An electron falling from any 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 ocular light is given off. This includes a variety of colour: red, orange, yellow, ballpark and blue. Finally when an electron falls down to superstar of the outer(prenominal) energy level such as the fourth one for example infra red light is given off. This is also not visible to the human eye. therefore we were unless qualified to interest electrons falling onto the second energy level. There were two unknowns in this experiment, which we had to identify tally to their spectra. This is merely an assumption, since the spectra of the elements be all very similar.

b)By doing this lab we also learned to look at elements according to the behavior of their electrons. As a result of this lab we now understand the Bohr model and wherefore we saw the different tincts of light in the flame. distinct elements gave off very different colors of light, which were even visible t o the naked eye. By simply doing the flame t! est we were able to tell that Lithium (which gives off bright red light), hog (which gives off bright green light) and Cesium (which gives off strike hard light) greatly differ. By looking at the periodic hold over we could whence testify our results, since we saw that these elements are all located utmost apart from each other. In articulate to see the color we added energy to...If you want to get a spacious essay, order it on our website: OrderEssay.net
