Niels Bohr, the 20th-century Nobel laureate Danish physicist, discovered and developed a realistic model of the atom, known as the Bohr model. Additionally, he developed the principle in quantum mechanics known as complementarity.Continue Reading
In the Bohr atomic model, a small nucleus of protons and neutrons is surrounded by electrons that maintain separate orbits, repelled by electronegativity. The electrons in this model can "jump" from one orbit to another when interacting with other energy sources.
The Bohr model was a combination of the Rutherford model of the atomic nucleus and Planck's quantum theories. It was largely supplanted over time by other models of atomic behavior, though it is used as a simple and fundamental description.Learn more about Inventions
A Bohr model of Yttrium is a representation of an atom of Yttrium. Yttrium was discovered by Johann Gadolin in 1794. It is named after a town in Sweden.Full Answer >
A Bohr diagram shows the distribution of an atom's electrons among different energy levels, or electron shells. Each diagram also features the number of protons and neutrons in the atom's nucleus.Full Answer >
Niels Bohr's greatest discovery was the atomic model. Bohr's model shows the atom as a positively charged nucleus surrounded by orbiting electrons. Bohr also discovered that electrons travel around the nucleus in distinct, concentric orbits.Full Answer >
Niels Bohr and Ernest Rutherford were the scientists who developed the planetary model of the atom, also referred to as the Bohr model. In 1913, Bohr published a theory, which was based on a previous theory of Rutherford’s.Full Answer >
