SUMMARY
The velocity of an electron in a hydrogen atom can be calculated using the centripetal force provided by the Coulomb's force between the electron and proton. Given the radius of the electron's orbit at 5.29 x 10^-11 m, the velocity is determined to be 2.19 x 10^6 m/s. The relevant equations include Coulomb's law, F = (Q1Q2)/(4πε0r^2), and the centripetal force equation, F = mv^2/r. By substituting the known values into these equations, one can derive the electron's velocity.
