Solution:
Shown below is a qualitative diagram of the atomic orbital energies for an Na atom. The number of orbitals in each subshell is not shown.A diagram shows that energy increases in the following order: 1s, 2s, 2p, 3s, 3p.
A sodium vapor lamp operates by using electricity to excite the highest-energy electron to the next highest-energy level. Light is produced when the excited electron drops back to the lower level. Which two energy levels are involved in this process for the Na atom?
