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 construction of physical models is often a creative act, and many bespoke examples have been carefully created in the workshops of science departments. There is a very wide range of approaches to physical modeling, including ball-and-stick models available for purchase commercially, to molecular models created using 3D printers. The main ...
This was in a gold atom known to be 10 −10 metres or so in radius—a very surprising finding, as it implied a strong central charge less than 1/3000th of the diameter of the atom. The Rutherford model served to concentrate a great deal of the atom's charge and mass to a very small core, but did not attribute any structure to the remaining ...
Real Steel is a 2011 American science fiction sports film starring Hugh Jackman and Dakota Goyo and co-produced and directed by Shawn Levy for DreamWorks Pictures.The film is based on the short story "Steel", written by Richard Matheson, which was originally published in the May 1956 edition of The Magazine of Fantasy & Science Fiction, and later adapted into a 1963 Twilight Zone episode.
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.
The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. [1]: 123 Thomson had discovered the electron through his work on cathode rays [2] and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series.

The position of each atom is determined by the nature of the chemical bonds by which it is connected to its neighboring atoms. The molecular geometry can be described by the positions of these atoms in space, evoking bond lengths of two joined atoms, bond angles of three connected atoms, and torsion angles ( dihedral angles ) of three ...
