Figure 4.9 J. J. Thomson’s plum pudding model of the atom states that the atom is a uniform, positively charged sphere containing electrons. JJ汤姆森的葡萄干布丁原子模型认为原子是一个均一带正电的球体,其中嵌入电子。 Figure 4.10 Development of Modern Atomic Theory 现代原子理论的发展 Current unde...
However, it’s strange that the name stuck. In Thomson’s model, electrons aren’t stationary like plums or seeds in their pulps. He proposed that they constantly move, or more precisely, rotate very rapidly. The orbits were stable because, as the electrons moved away from the center of t...
In what year was the nucleus discovered and why did this impact JJ Thomson's model 1911, and because it showed that the negative and positive charges did not exist in the same sphere of existence, and the positive charges were housed inside the nucleus The best way to study. Sign up fo...
Rutherford discovered the nucleus and introduced a new model using both electrons and the nucleus. The main difference between the Thomson and Rutherford model of an atom is that the Thomson model of an atom does not contain any details about the nucleus whereas the Rutherford model of...
J.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom. He deve

Thomson invented the electron by playing with a tube that was Crookes, or cathode ray. He had shown that the cathode rays were charged negatively. Thomson realized that the accepted model of an atom did not account for the particles charged negatively or positively. Q4 What are the ...
