A. Calculation of the Energy Levels of the Hydrogen Atom Given the expression for En in Equation 6, it is possible to calculate the energy for each of the allowed levels of the Hatom starting with n = 1. Using your calculator, calculate the energy in kJ/mole of each of the 10 lowest levels of the H atom. Note that the energies are all negative, so that the lowest energy will have the largest allowed negative value. Enter these values in the table of energy levels, Table 11.2. On the energy level diagram provided just before the ASA, plot along the y-axis each of the six lowest energies, drawing a horizontal line at the allowed level and writing the value of the energy alongside the line near the y-axis. Write the quantum number associated with the level to the right of the line. B. Calculation of the Wavelengths of the Lines in the Hydrogen Atomic Spectrum The lines in the hydrogen spectrum all arise from jumps made by the atom from one energy level to another. The wavelengths in nm of these lines can be calculated by Equation 4, where AE is the difference in energy in kJ/mole between any two allowed levels. For example, to find the wavelength of the spectral line associated with a transition from the n=2 level to the n=1 level, calculate the difference, AE, between the energies of those two levels. Then substitute AE into Equation 4 to obtain this wavelength in nanometers. Using the procedure we have outlined, calculate the wavelengths in nm of all the lines we have indicated in Table 11.3. That is, calculate the wavelengths of all the lines that can arise from transitions between any two of the six lowest levels of the H atom. Enter these values in Table 11.3. C. Assignment of Observed Lines in the Hydrogen Atomic Spectrum Compare the wavelengths you have calculated with those listed in Table 11.1. If you have made your calculations properly, your wavelengths should match, within the error of your calculation, several of those that are observed. On the line opposite each wavelength in Table 11.1, write the quantum numbers of the upper and lower states for each line whose origin you can recognize by comparison of your calculated values with the observed values. On the energy level diagram, draw a vertical arrow pointing down (light is emitted, meaning energy leaves the atom and AEatom

Explanation & Answer

Have a look at it and get back to me. In calculation 1e, there is something lacking please sent it so that I finish it. For qn 2e, I had skipped it that's why I squeezed it there, side. Thnaks

A. Calculation of the Energy Levels of the Hydrogen Atom
1. Using the expression for En in Equation 6, calculate the energy in kJ/mole
of each of the 10 lowest levels of H atom starting with n=1. The energy
values will be negative. The lowest energy will have the largest allowed
negative value.
2. Enter these energy values in the table of energy levels, Table 11.2.
3. On the energy level diagram provided just before ASA, pot each of the six
lowest energies along the y-axis.
4. Draw a horizontal line at the a...
