Question

(a) Calculate the time required for an electron in the n = 2 state of hydrogen to complete one orbit about the
nucleus. (b) The typical “lifetime” of an electron in the n = 2 state is roughly 10−8
s—after this time the
electron is likely to have dropped back to the n = 1 state. Estimate the number of orbits an electron completes in
the n = 2 state before dropping to the ground state.
