Final answer:
The statement is true; Bohr's model correctly assigns energy levels to electrons. While it worked well for the hydrogen atom, it was not generalizable to other elements and was later superseded by quantum mechanical models.
Step-by-step explanation:
The statement that Bohr's model was correct in assigning energy levels to electrons is true. Niels Bohr suggested that electrons in an atom are restricted to specific orbits, with each orbit corresponding to a definite energy level. These orbits are unchangeable, and for an electron to be in one, it must have the precise amount of energy designated for that orbit. Transitioning between orbits involves the absorption or emission of energy, corresponding to the difference between the energy levels.
However, while Bohr's model offered a meaningful contribution to atomic theory and was successful in explaining the hydrogen atom's spectra, it had limitations. The model could not justify why only certain orbits were allowed, and it was not accurate for atoms other than hydrogen. Nonetheless, the concept of quantized energy levels remains fundamental in quantum theory, albeit with a more sophisticated understanding of electron behavior.
