1. Demonstrate that Bohr's model of the hydrogen atom is well approximated by a classical particle model (classical physics) in the case of very large quantum numbers (while ignoring Maxwell’s system of equations for charged particles). Show all intermediate algebraic steps. (5 points)

2. Elaborate on the meaning of the empirical constants A_n and b in "Moseley's law/rule" for K_α radiation on the basis of a "quasi-Bohr model generalization for heavy atoms", i.e. 2 electrons at most in the lowest orbit (with quantum number 1) before excitation. (2 points). Why is it justified to use the Rydberg energy for infinitely heavy nuclei in your elaboration? (1 point). Which physical constants are needed to explain the numerical value of A_n ?
