The Bohr Model

Niels Bohr, a Danish physicist, made significant contributions to atomic theory, notably the Bohr model introduced in 1913. This model depicted atoms with electrons orbiting a positively charged nucleus, similar to planets around the sun. Electrons move in set paths based on energy levels, and transitions between these levels result in light emission. Bohr's model laid the foundation for modern atomic understanding, and its simplicity and utility have kept it relevant. Key points include specific energy levels for orbitals, non-classical electron movement, and light emission during electron transitions.
