Bohr ring
Niels Bohr's theory of the atom proposed that electrons move around the nucleus in specific, fixed paths called orbits or energy levels. These orbits have specific energy levels and are sometimes referred to as shells.

Bohr's model
Niels Bohr placed in the center of atom the atomic nucleus and electrons in movement around nucleus.
Niels Bohr proposed the theory that electrons move in specific energy levels or shells around the nucleus of an atom. This model, known as the Bohr model, was based on his work with the hydrogen atom and was published in 1913.
