Lesson Worksheet: Atomic Emission Spectra Chemistry • 10th Grade

In this worksheet, we will practice labeling the lines in atomic emission spectra and linking their positions to electronic transitions in hydrogenic atoms.

Q1:

The visible lines of the atomic emission spectrum for hydrogen are produced by electronic transitions to a common energy level. What is the principal quantum number 𝑛 for this energy level?

Q2:

Which of the following series of electronic transitions in the hydrogen atom produces spectral lines with the shortest wavelengths?

  • ALyman series
  • BBrackett series
  • CBalmer series
  • DPfund series
  • EPaschen series

Q3:

In which series of electronic transitions in the hydrogen atom does the lower energy level have the principal quantum number 𝑛=4?

  • APfund series
  • BBrackett series
  • CLyman series
