A hydrogen atom has a radius of about 0.05 nm.
(a) Estimate the uncertainty in any component of the momentum of an electron confined to a region of this size.
kg · m/s
(b) From your answer to (a), estimate the electron's kinetic energy in three dimensions.
eV
(c) Does the estimate have the correct order of magnitude? (The ground-state kinetic energy predicted by the Bohr model is 13.6 eV.)
