What did Thomson find?

Thomson's research discovered electrons and put forward an atomic model. These discoveries had a far-reaching impact on the development of modern physics and atomic theory, so he was awarded the Nobel Prize in Physics of 1906.

Thomson is a British physicist. He made many important discoveries in the research of 19 and the beginning of the 20th century. The most famous is his electronic discovery.

By conducting cathode ray experiments, Thomson proved the existence of a negatively charged particle, which we now call an electron. This discovery had an important influence on the later development of atomic theory and electronics.

In addition, Thomson also proposed a loose atomic model, namely watermelon cake model or fluctuation point model. According to his observation and experimental results, he thinks that atoms are composed of electrons distributed in a uniformly charged cloud. This model provided the basis for the later atomic structure theory, and was further improved and developed by later scientists.

Introduction to Thomson

Thomas Thomson Joseph John (1856-1940), a British physicist, is regarded as one of the discoverers of electrons and one of the founders of atomic structure theory.

Thomson was born in Chelsea, near Manchester, England, on June 1856+1February/8. He was educated at Manchester University, where he spent most of his career. He became a professor of natural philosophy from 65438 to 0884, and held this position for 35 years.

1897, Thomson conducted a cathode ray experiment and found negatively charged particles, namely electrons. He obtained the basic characteristics of electrons such as charge-to-mass ratio by measuring the motion properties of cathode rays and the deflection of magnetic field. This discovery has played a milestone role in understanding the importance of atomic and electronic structures.

In addition, Thomson also put forward the famous watermelon cake model or fluctuation point model, which compared atoms to a uniform cloud with positive charges and electrons distributed in it. This model laid the foundation for the later atomic structure theory and provided guidance for the further development of scientists.

Thomson's outstanding contribution made him a famous figure in the scientific community at that time. He was awarded the Nobel Prize in Physics in 1906 in recognition of his discovery of electrons and his contribution to the atomic structure. He also served as the president of the Royal Society and won many honors and medals.

Thomson died on August 30th, 1940 at the age of 83. His research and discovery have had a far-reaching impact on modern physics, atomic physics, electronics and other fields, and made important contributions to future scientific research.
