Bohr's contribution to atomic theory

WebContribution to atomic theory. Bohr's model introduced the quantum mechanics. Quantum mechanics attempts to describe and account for the properties of molecules and atoms and their constituents; electrons, protons, neutrons and other subatomic partials. He was the first to discover that electrons travel in specific orbits. Although, Bohr's ... WebDalton's ideas proved foundational to modern atomic theory. However, one of his underlying assumptions was later shown to be incorrect. Dalton thought that atoms were the smallest units of matter −-− minus tiny, hard spheres that could not be broken down any further. This assumption persisted until experiments in physics showed that the atom …
