Explain why you are constructing a graph for krypton emission lines but not for hydrogen.

Solutions

Expert Solution

The krypton (Kr) spectrum is characterized mainly by two brilliant lineas (green and yellow) but also has several emission lines (less intense). On the other side, hydrogen (H) only has four spectral lines due to energy levels.

The difference here is because H has 1 electron but Kr has 36 electrons, the emission spectral lines is more complicated for the last one, than the H, since 36 electron has many energy levels for each one. But we can actually construct both spectra, we can obtain them experimentally with a discharge tube and a spectroscope. And also we can use the specra to indentify unknown elements.

Should the Bohr model predict the correct emission lines for the He+ ion ? Why or why not? Use the Bohr model to predict some of the visible emission lines of the He+ ion.

Then calculate the wavelengths in nm corresponding to the transitions n=4→3, and n=6→4. Can either of these be observed in your He emission spectrum?
