1. In the Emission Spectra tool, select each element to see its emission spectrum.
2. In the data table below, record the element symbol, atomic number, the
lowest wavelength present in the spectrum (in nanometers), the highest
wavelength in the spectrum (in nanometers), and the total number of lines in
the spectrum.
3. Watch for any patterns in the spectra. For example, is there any correlation
between an element’s atomic number and the lowest or highest wavelength
in its spectrum? Do larger elements consistently have more spectral lines?
