Which of the following statements regarding the Bohr model of the hydrogen atom is incorrect? A. Bohr's model shows the electron circling the nucleus in fixed orbits. B. In Bohr's model, electrons could exist between orbits. C. In Bohr's model, when an electron absorbs energy, it can move to a higher-energy orbit. D. In Bohr's model, when an electron emits energy, it can move to a lower-energy orbit. E. In Bohr's model, n = 1 is the lowest energy orbit.
