Niels Henrik David Bohr, född 7 oktober 1885 i Köpenhamn, död 18 november 1962 i Köpenhamn, var en av 1900-talets främsta atomfysiker. 1913 publicerade Bohr, inspirerad av Plancks och Einsteins arbeten, en atommodell som bortsåg från den klassiska fysikens begrepp. Modellen byggde på en hypotes om elektronernas stationära tillstånd, som svarade mot en diskret serie av energivärden. Den primitiva men lyckade modellen, kallad Bohrs atommodell, öppnade för en flodvåg av
The Bohr Model was the first theory used to correctly describe the structure of hydrogen, the simplest atom. It was introduced by Niels Bohr in 1913 to show a positively charged nucleus (where the protons and neutrons reside) surrounded by an electron cloud with a negative charge.

Because the Bohr Model is a modification of the earlier Rutherford Model, some people call Bohr's Model the Rutherford-Bohr Model. The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version.
Bohrs atommodel fra 1913 blev formuleret af den danske fysiker Niels Bohr.. I denne model er atomet arrangeret som en atomkerne med en positiv ladning, omkredset af negative elektroner, på stort set samme måde som solsystemet, men med elektrostatiske tiltrækningskræfter i stedet for massetiltrækning.

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. The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only
