Sodium nitrate is one kind of color agents in fireworks. Its energy level spectrum is given below. When sodium nitrate is heated, the electrons of the sodium atoms absorb heat energy and become excited. This high-energy excited state does not last for long, and the excited electrons of the sodium atom quickly release their energy, which is the energy of certain light. 1. What's the quantum numbers for states like 5S1/2, 4P3/2 ? Explain them in details. 2. Give the electron configuration / arrangement of sodium ground state. 3. Find the excited state with the lowest energy. Calculate the exact wavelength of this transition using the relation E=hν and c=λν. 4. Tell the color of this emission.
