The kinetic energy of an electron in a particular Bohr orbit of hydrogen is 1.35 × 10-19 J.
(a) Which Bohr orbit does the electron occupy?
(b) Suppose the electron moves away from the nucleus to the next higher Bohr orbit. Does the kinetic energy of the electron increase, decrease, or stay the same? Explain.
(c) Calculate the kinetic energy of the electron in the orbit referred to in part (b).
