How many spectral lines does helium have

Web10 okt. 2024 · In emission spectra, bright lines will show up corresponding to the difference between energy levels of the elements, where in an absorption spectrum, the lines will be dark. By looking at the pattern of lines, scientists can figure out the energy levels of the elements in the sample. WebHelium showed 7 emission lines: two red, yellow, two green, indigo, and violet. The difference in emission lines are caused by the fact that helium has more electrons than hydrogen does. Hydrogen has only 1 while helium has 2. With more electrons being excited, more spectral lines will be observed.
