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. Thomson's model had ...
English: Model of the atom by Ernest Rutherford. He proposed a nucleus with protons and electrons spinning around. He proposed a nucleus with protons and electrons spinning around. Work done by David Marin with the scientific supervision of José Carlos Sánchez Muñoz, a chemist at the School of Engineering of Seville .
The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. [2]: 123 Thomson had discovered the electron through his work on cathode rays [3] and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series.
Rutherford's model, being supported primarily by scattering data unfamiliar to many scientists, did not catch on until Niels Bohr joined Rutherford's lab and developed a new model for the electrons. [54]: 304 Rutherford model predicted that the scattering of alpha particles would be proportional to the square of the atomic charge.
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.
Rutherford (unit), a unit of radioactivity; Rutherford scattering, a phenomenon in physics which led to the development of the Rutherford model (or planetary model) of the atom and eventually to the Bohr model; Rutherford (lunar crater), a small impact crater on the Moon ' s far side; Rutherford (Martian crater), a crater on Mars
1916 Gilbert N. Lewis and Irving Langmuir formulate an electron shell model of chemical bonding; 1917 Albert Einstein introduces the idea of stimulated radiation emission; 1918 Ernest Rutherford notices that, when alpha particles were shot into nitrogen gas, his scintillation detectors showed the signatures of hydrogen nuclei.
Element 104 was eventually named after Ernest Rutherford Igor Kurchatov As a consequence of the initial competing claims of discovery, an element naming controversy arose. Since the Soviets claimed to have first detected the new element they suggested the name kurchatovium (Ku) in honor of Igor Kurchatov (1903–1960), former head of Soviet ...
