A Bohr model is a diagram that depicts an atom’s structure, with a nucleus surrounded by electrons arranged in concentric circles. It was developed by Niels Bohr in 1913 and provided the first successful explanation for the behavior of electrons in atoms.
Bohr models are important because they provide a simple and intuitive way to visualize the structure of atoms. They are also useful for understanding the chemical properties of elements and for predicting the behavior of atoms in chemical reactions.
