Niels Bohr and Ernest Rutherford proposed the Rutherford–Bohr model, often simply called the Bohr model, where electrons occupy orbits around the nucleus like the planets around the sun. This explained the features of the emission spectrum of hydrogen.
Vor 2 Tagen · In 1913, the physicist Niels Bohr proposed a model in which the electrons of an atom were assumed to orbit the nucleus but could only do so in a finite set of orbits, and could jump between these orbits only in discrete changes of energy corresponding to absorption or radiation of a photon.

Vor 2 Tagen · The interaction with virtual particles also explains the small (about 0.1%) deviation of the intrinsic magnetic moment of the electron from the Bohr magneton (the anomalous magnetic moment). [82] [103] The extraordinarily precise agreement of this predicted difference with the experimentally determined value is viewed as one of the great achievements of quantum electrodynamics .
Vor 5 Tagen · In 1913, physicists Niels Bohr and Ernest Rutherford proposed the Rutherford–Bohr model, which is now commonly referred to simply as the Bohr model. The model describes electrons as small negatively charged particles orbiting a dense, positively charged nucleus.
Matteucci-Medaille. Die Matteucci-Medaille ( ital. Medaglia Matteucci) ist nach dem italienischen Physiker Carlo Matteucci (1811–1868) benannt, der sie auch initiiert hatte. Sie wird jährlich von der Accademia Nazionale delle Scienze an Physiker verliehen, die grundlegende Beiträge zur Wissenschaft lieferten. Am 10.
Vor 3 Tagen · Werner Karl Heisenberg ( pronounced [ˈvɛʁnɐ kaʁl ˈhaɪzn̩bɛʁk] ⓘ; 5 December 1901 – 1 February 1976) [2] was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II.
Vor 4 Tagen · 1. Discuss the history of the model: Begin by introducing your students to the history of the atom model. Give a brief account of the theories and experiments conducted by various scientists in the 1800s and early 1900s, such as J.J. Thompson, Ernest Rutherford, and Niels Bohr, who contributed to the understanding of atomic structure. 2 ...
