Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus. Electrons move in fixed orbits, called electron shells ...
