Web8 sep. 2024 · In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. WebSince atoms rarely occur in isolation this electron is taken by a neighn=bouring atom making that atom an anion. Note: this energy to remove an electron from the atom is known as ionization enthalpy of the element and is a characteristic of nuclear pull on the electron.
