1. What causes each line to appear?
Each line is able to appear because an excited electron was unstable and had to fall back to a more stable energy level, creating energy in the form of light. However, to understand this, one must understand what causes an electron to be excited. So from the very beginning, a person named Max Plank proposed a theory that energy is emitted and absorbed in quantities called “quanta.” Einstein then came along and said that light contained quanta energy called “photons.” Electrons that are present in atoms are on different energy levels, with the lowest level that is closest to the nucleus being called the “ground state.” If an electron gains enough energy, it will jump to a higher energy level called the “excited state.” When an electron becomes excited, it becomes unstable and has to fall back to a more stable level. When they fall back, energy is created in the form of …show more content…
I identified it as Hydrogen through the spectrometer and counting the number of lines that showed up inside it. I first looked at the sample and then counted the lines that showed up inside the spectrometer. The number I got for that was 3. The numbers that I got for each of the lines were 450, 500, and 680. Then I went to the back of the sheet that I was recording the data and compared my numbers. I immediately eliminated many possible elements because the elements had too many numbers; I only needed elements that had 3 numbers. As I went down the list of possible elements, I saw the element Hydrogen had very close numbers to the ones that I had written down (440, 490, 670 respectively) so I compared my numbers with the rest of the elements. None of the other elements came close to the similarity with Hydrogen so I concluded that Hydrogen was sample #4 because my numbers and the numbers of Hydrogen written on the back of the sheet were only each 10 nm
