Which of the following best explains why the Bohr model predicts only certain discrete orbital radii for the electron in a hydrogen atom?
(a) The centripetal force on the electron equals the electrostatic attraction only at certain orbital radii, restricting the possible orbits.
(b) The electron’s matter wave must form a standing wave whose circumference equals an integer multiple of its wavelength.
(c) The electron’s de Broglie wavelength must fit an integer number of wavelengths along the diameter of the orbit.
(d) The Coulomb potential energy between the nucleus and electron is itself quantized, permitting orbits only when it equals an integer multiple of a fundamental unit.
