Problem
A researcher measures the distance of closest approach between an external probe and the electron cloud of a hydrogen atom. To interpret the measurement, the researcher needs numerical values for the first three allowed radii of hydrogen and the corresponding electron speeds.
(a) Determine the radii r1, r2, and r3 for the hydrogen atom. Provide each answer in meters to three significant figures.
(b) Compute the ratios r2/r1 and r3/r2. Comment on the mathematical pattern you observe.
(c) Calculate the speed of the electron in the n=1 orbit of hydrogen. Express your answer in meters per second to three significant figures.
