Tang Musun put forward a model of atomic structure or something.

Tang Musun put forward "raisin cake" model, "watermelon" model and "pudding" model with atomic structure.

Atoms are very small, about one millionth of a millimeter in diameter. They consist of a nucleus at the center of the atom and some tiny electrons. These electrons move around the center of the nucleus, just as the planets in the solar system move around the sun. And atoms are the same as any black particle in the universe.

Research process

Lord Kelvin (1824 ~ 1907), a famous British physicist and inventor, was originally named William Tang Musun. Because of his meritorious service in installing the first Atlantic submarine cable, the British government awarded him a knighthood in 1866 and was promoted to Lord Kelvin in 1892.

Kelvin's research has a wide range, and he has made contributions in the fields of heat, electromagnetism, fluid mechanics, optics, geophysics, mathematics and engineering applications. He published more than 600 papers in his life and obtained 70 invention patents. He enjoyed a high reputation in the scientific community at that time.

Kelvin 1902 put forward the atom model of solid charged sphere, that is, the atom is regarded as a uniformly positively charged sphere with negatively charged electrons buried in it, which is in electrostatic equilibrium under normal conditions. This model was later developed by J.J. Tang Musun, and later called Tang Musun Atomic Model.

In this model proposed by Thomson, the distribution of electrons in the sphere is a bit like raisins dotted in a cake. Many people call Thomson's atomic model "raisin cake model".

It can not only explain why atoms are electrically neutral and how electrons are distributed in atoms, but also explain cathode ray phenomenon and the phenomenon that metals can emit electrons under ultraviolet radiation. Moreover, according to this model, it can be estimated that the size of the atom is about 10-8 cm, which is an amazing thing. Because Thomson model can explain many experimental facts at that time, it is easily accepted by many physicists.
