    29. Apr. 2024 · Niels Bohr (born October 7, 1885, Copenhagen, Denmark—died November 18, 1962, Copenhagen) was a Danish physicist who is generally regarded as one of the foremost physicists of the 20th century. He was the first to apply the quantum concept, which restricts the energy of a system to certain discrete values, to the problem of atomic and ...

    2. Mai 2024 · Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr. The Bohr model of the atom , a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.

    7. Mai 2024 · The Bohr model of the atom tells us that the angular momentum 𝐿 of an electron in an atom is quantized. Specifically, it tells us that 𝐿 can only be an integer multiple of the reduced Planck constant ℏ. This is expressed by the equation 𝐿 = 𝑛 ℏ, where 𝑛 is a positive integer known as the principal quantum number.

    2. Mai 2024 · Mit Korrespondenzprinzip wurde ursprünglich eine Beziehung zwischen Termini der klassischen Physik und der Quantenmechanik bezeichnet. Der Ausdruck wurde 1920 von Niels Bohr im Kontext der älteren Quantentheorie geprägt. [1] Es wird in diesem Zusammenhang auch als Bohrsches Korrespondenzprinzip bezeichnet.
