  2. Bohr model - Wikipedia

    en.wikipedia.org/wiki/Bohr_model

    In atomic physics, the Bohr model or Rutherford–Bohr model was the first successful model of the atom. Developed from 1911 to 1918 by Niels Bohr and building on Ernest Rutherford 's nuclear model , it supplanted the plum pudding model of J. J. Thomson only to be replaced by the quantum atomic model in the 1920s.

  3. Atomic orbital - Wikipedia

    en.wikipedia.org/wiki/Atomic_orbital

    Atomic orbitals are basic building blocks of the atomic orbital model (or electron cloud or wave mechanics model), a modern framework for visualizing submicroscopic behavior of electrons in matter. In this model, the electron cloud of an atom may be seen as being built up (in approximation) in an electron configuration that is a product of ...

  4. File:Bohr Model.svg - Wikipedia

    en.wikipedia.org/wiki/File:Bohr_Model.svg

    I created this file to be an SVG alternative to Image:Bohratommodel.png and Image:Bohr model Balmer 32.png. I did not draw the orbitals to scale like the latter diagram because I could not readily find information about the orbitals' radii. For some reason, the "+" on the nucleus is rendering off-centered. The SVG doesn't look like that.

  6. History of atomic theory - Wikipedia

    en.wikipedia.org/wiki/History_of_atomic_theory

    In a trilogy of papers Bohr described and applied his model to derive the Balmer series of lines in the atomic spectrum of hydrogen and the related spectrum of He +. [37]: 197 He also used he model to describe the structure of the periodic table and aspects of chemical bonding. Together these results lead to Bohr's model being widely accepted ...

    Bahasa Melayu: Model Bohr dari atom hidrogen menggambarkan elektron-elektron bermuatan negatif mengorbit pada kulit atom dalam lintasan tertentu mengelilingi inti atom yang bermuatan positif. Ketika elektron meloncat dari satu orbit ke orbit lainnya selalu disertai dengan pemancaran atau penyerapan sejumlah energi elektromagnetik hf.

  9. Rutherford model - Wikipedia

    en.wikipedia.org/wiki/Rutherford_model

    The Rutherford model is a name for the first model of an atom with a compact nucleus. The concept arose from Ernest Rutherford discovery of the nucleus. Rutherford directed the Geiger–Marsden experiment in 1909, which showed much more alpha particle recoil than J. J. Thomson 's plum pudding model of the atom could explain.
