1 giorno fa · Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
2 giorni fa · Come accennato il modello atomico di Bohr rappresenta in modo realistico soltanto la struttura dell’idrogeno. Il totale dell’energia posseduta dal suo elettrone deriva dalla somma della sua energia potenziale ( EP) e della sua energia cinetica (EC). Per trovare l’energia potenziale bisogna utilizzare la formula Ep = e2/r.
29 apr 2024 · Niels Bohr, 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 to the problem of atomic and molecular structure.

2 mag 2024 · Bohr model, description of the structure of atoms proposed in 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.

1 giorno fa · Niels Bohr explained around 1913 that electrons might revolve around a compact nucleus with definite angular momentum. Bohr's model was an improvement on the 1911 explanations of Ernest Rutherford , that of the electron moving around a nucleus.
4 giorni fa · In 1913, Niels Bohr, a Danish physicist, introduced the concepts of quantum mechanics to atomic structure by proposing what is now known as the Bohr model of the atom, where electrons exist only in strictly defined circular orbits around the nucleus similar to rungs on a ladder.
