Niels Bohr and the Rutherford model

The video discusses the evolution of atomic models, starting with Rutherford's model, which introduced electrons orbiting a nucleus but had stability issues. Niels Bohr refined this in 1913 by proposing that electrons travel in fixed orbits without radiating energy, similar to planets around the Sun. Each orbit corresponds to a specific energy level, and electrons can move between levels by absorbing or emitting energy as photons. Bohr's model accurately described hydrogen and laid the groundwork for the quantum mechanical model of the atom.
