The Life Story of J.J. Thomson: Biography, Electron Discovery, Cathode Ray Tube Experiment—Class 12

Описание: In this video, we discuss the biography and life story of scientist J. J. Thomson, whose discovery of the electron still influences chemistry and physics today. During his time at Cambridge University, JJ Thomson studied subatomic particles and proved earlier scientists in the history of atomic theory, such as Dalton's atomic theory, wrong. The plum pudding model, developed by Thomson, proposed that electrons are embedded in a positively charged environment. We also discuss the question, "what are the limitations of JJ Thomson's model of the atom" and how later scientists, such as Ernest Rutherford, built on this model with more advanced theories. The discovery of the electron by JJ Thomson remains an important step in the development of atomic theory.

This video is for Class 11 and Class 12 students of the atomic model and theory in physics and chemistry. If you want to know more about the question, "Who is JJ Thomson", this lecture is for you. This brief documentary shows how J.J. Thomson discovered the electron by studying cathode rays. We explained it in simple words, with the goal of keeping the explanation straightforward.

We provide science lessons and PDF worksheets for Classes 9, 10, 11, as well as a level. We hope you enjoy this chemistry lecture!
