If the outermost electron in an atom is excited to a very high energy state, its orbit is far beyond that of the other electrons. To a good approximation, we can think of the electron as orbiting a compact core with a charge equal to the charge of a single proton. The outer electron in such a Rydberg atom thus has energy levels corresponding to those of hydrogen. a. What is the radius of the n = 100 state of the Bohr hydrogen atom?b. Sodium is a common element for such studies. How does the radius you calculated in part a compare to the approximately 0.2 nm radius of a typical sodium atom?
