Sample Test Problems

1. Write down the electron configuration and ground state for the elements from $Z=1$ to $Z=10$. Use the standard $^{2s+1}L_j$ notation.

2. Write down the ground state (in spectroscopic notation) for the element Oxygen ($Z=8$).

3. A Florine (Z=9) atom is in its ground state. Write the state in spectroscopic notation. (Ignore the spin of the nucleus.) A weak magnetic field is applied splitting the state. How many energy levels are there now? What is the gyromagnetic ratio for the ground state of Florine.
