WebThe concept of the atom that Western scientists accepted in broad outline from the 1600s until about 1900 originated with Greek philosophers in the 5th century bce. Their speculation about a hard, indivisible fundamental particle of nature was replaced slowly by a scientific theory supported by experiment and mathematical deduction. It was more than 2,000 … WebThe composition of the atom. In the classical model, the atom is composed of smaller particles with an electrical charge known as electrons and protons. The atom also features a third, neutral kind of particle known as neutrons. Atomic models seek to understand how these particles make up the atom. The classical atom composition is as follows:

WebExpert Answer. Models of the Hydrogen Atom One of the most tantalizing puzzles at the beginning of the 1900 s was how to describe the atom. This begins by first observing a simulated light spectrum of hydrogen. You will then look at spectra predicted by different models of the atom. Historicul models of the atom include: - John Dalton's ... WebThe prevailing theory of atomic structure at the time of Rutherford's experiments was the "plum pudding model".This model was devised by J. J. Thomson.Thomson had discovered the electron and believed that every atom was a sphere of positive charge throughout which the electrons were distributed, a bit like raisins in a Christmas pudding.The existence of … WebSir J.J Thomson gave the first model of atom. He by means of cathode-ray experiment discovered the existence of negatively charged particles in an atom which led to the discovery of electrons. He gave the plum-pudding model of an atom in which electrons are embedded in atom-like currants. Positive electrons are distributed all over the atom. hiking trails near asotin
