Which of the following statements is not consistent with the Bohr theory?
a. An electron may move to a lower energy orbit by emitting radiation of frequency proportional to the energy difference between the two orbits.
b. The energy of an electron is quantized
c. An atom has a number of discrete energy levels (orbits) in which an electron can exist as long as it continually emits radiation of a definite energy
d. An electron moves in a circular orbit around the nucleus
e. An electron may move to a higher energy orbit by absorbing radiation of frequency proportional to the energy difference between the two orbits.
Answer: C
