Within the Bohr model of the hydrogen atom, the radius of the orbit for the ground state was 5.292 x 10-11 m. Using de Broglie's idea that the circumference of this orbit had to equal the wavelength of the electron, calculate the kinetic energy (in J) of the electron in a ground state hydrogen atom?
