What statement did Neil Bohr make about atoms?

Niels Bohr famously stated that "an atom is like a small solar system," where electrons orbit the nucleus much like planets orbit the sun. He introduced the Bohr model of the atom in 1913, which proposed that electrons exist in specific energy levels or orbits and can jump between these levels by absorbing or emitting energy. This groundbreaking view contributed significantly to the development of quantum mechanics and our understanding of atomic structure.
