Highly excited atoms have electrons with large principal quantum numbers. Such Rydberg atoms have unique properties and are of interest to astrophysicists. (a) For hydrogen atoms with large n, derive a relation for the separation of energy levels. (b) Calculate this separation for n = 100; also calculate the average radius (see the preceding activity), and the ionization energy. (c) Could a thermal collision with another hydrogen atom ionize this Rydberg atom? (d) What minimum velocity of the second atom is required? (e) Sketch the likely form of the radial wavefunction for a 100s orbital.
