A Bohr mannequin is a diagram that depicts an atom’s construction, with a nucleus surrounded by electrons organized in concentric circles. It was developed by Niels Bohr in 1913 and offered the primary profitable rationalization for the conduct of electrons in atoms.
Bohr fashions are necessary as a result of they supply a easy and intuitive option to visualize the construction of atoms. They’re additionally helpful for understanding the chemical properties of parts and for predicting the conduct of atoms in chemical reactions.
