An atom with seven electrons arranged in a pentagonal dipyramid, as imagined by Thomson in 1905. The plum pudding model is an obsolete scientific model of the atom.It was first proposed by J. J. Thomson in 1904 following his discovery of the electron in 1897, and was rendered obsolete by Ernest Rutherford's discovery of the atomic nucleus in 1911.
Thomson's prize-winning master's work, Treatise on the motion of vortex rings, shows his early interest in atomic structure. [3] In it, Thomson mathematically described the motions of William Thomson's vortex theory of atoms. [17] Thomson published a number of papers addressing both mathematical and experimental issues of electromagnetism.
The Thomson problem is a natural consequence of J. J. Thomson's plum pudding model in the absence of its uniform positive background charge. [ 12 ] "No fact discovered about the atom can be trivial, nor fail to accelerate the progress of physical science, for the greater part of natural philosophy is the outcome of the structure and mechanism ...
[4] [5] In it, Thomson developed a mathematical treatment of the motions of William Thomson and Peter Tait's atoms. [6] When Thomson later discovered the electron (for which he received a Nobel Prize), he abandoned his "nebular atom" hypothesis based on the vortex atomic theory, in favour of his plum pudding model.
This led to a series of atomic models with some quantum aspects, such as that of Arthur Erich Haas in 1910 [37]: 197 and the 1912 John William Nicholson atomic model with quantized angular momentum as h/2 π. [58] [59] The dynamical structure of these models was still classical, but in 1913, Bohr abandon the classical approach.
The term atomic physics can be associated with nuclear power and nuclear weapons, due to the synonymous use of atomic and nuclear in standard English. Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics , which studies nuclear reactions and special ...
When Bohr began his work on a new atomic theory in the summer of 1912 [8]: 237 the atomic model proposed by J J Thomson, now known as the Plum pudding model, was the best available. [9]: 37 Thomson proposed a model with electrons rotating in coplanar rings within an atomic-sized, positively-charged, spherical volume. Thomson showed that this ...
An early scale model created for testing the ballistics of the "Thin Man" gun-type atomic bomb. These early tests used 14/23 scale models made from a standard 500 lb gravity bomb, a 14" diameter pipe, and a box tail. The results were extremely poor. The great length of the Thin Man bomb led to aerodynamic instabilities.
