The Bohr Model: Advancements in Understanding the Atom

In 1913, Niels Bohr enhanced Rutherford's atomic model by proposing that electrons move in specific orbits around the nucleus, with these orbits representing different energy levels. This model, known as the Bohr model, provided a clearer understanding of atomic structure by specifying electron locations relative to the nucleus.
