Witryna15 lut 2024 · The plum pudding model of J. J. Thomson could not able to explain certain experimental results about the atomic structure of elements. still, there was no clear model that defines atoms, therefore in 1909, Ernest Rutherford, a British scientist conducted an experiment and based on the experiment he observed and proposed … On 22 December 1884, Thomson was appointed Cavendish Professor of Physics at the University of Cambridge. The appointment caused considerable surprise, given that candidates such as Osborne Reynolds or Richard Glazebrook were older and more experienced in laboratory work. Thomson was known for his work as a mathematician, where he was recognized as an exceptional tale…

WitrynaThomson knew that atoms had an overall neutral charge. Therefore, he reasoned that there must be a source of positive charge within the atom to counterbalance the … WitrynaThomson's claim to be the discoverer of the electron rests on two key observations. First, he found that the value of e/m was of the order of 1000 times larger than its value for the lightest particle then known, which was the hydrogen ion in electrolysis.

J. Thomson in 1897 and the experimental demonstration by his son G. P. Thomson in 1927 that the electron exhibits the properties of a wave. Together, the Thomsons are two of the most significant figures in modern …
WitrynaDuring the 1880s and ’90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897. The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous particle was wrong and …
