Question

How can elements with low atomic numbers
have so many spectral lines?
1. Elements with low atomic numbers usu-
ally don't react chemically with other ele-
ments.
2. Elements with low atomic numbers have
many free electrons.
3. Elements with low atomic numbers have
small masses.
4. Electrons can be boosted to many energy
levels, thus making many different transitions
to ground level and levels between.

1. The two prominent yellow lines in the spectrum of sodium result from transitions to the ground state from the 3p state with the electron spin-up, and from the 3p state with the electron spin-down. The wavelengths these two lines are 589.0 nm and 589.6 nm. (a) Calculate the energies in eV of the photons corresponding to these wavelengths, and the difference in energy of these photons AE. (b) The energy difference you found in part (a) is due to the spin-orbit effect. An electron in the 3p state of sodium experiences an internal magnetic field B, due to the orbital angular momentum. For a magnetic field B₁, the spin-orbit energy splitting is AE = 2µBB₁, where B is the Bohr magneton. Find the orbital magnetic field By from the energy difference AE you found in part (a).
