FAQs on Quick Revision: Atomic Models: Thomson & Rutherford Video Lecture - Chemistry Class 11 - NEET

1. What is the Thomson atomic model?
Ans. The Thomson atomic model, also known as the "plum pudding model," proposed that electrons are embedded in a positively charged sphere like plums in a pudding.
2. Who proposed the Rutherford atomic model?
Ans. The Rutherford atomic model was proposed by Ernest Rutherford in 1911 based on the gold foil experiment.
3. What was the key finding of Rutherford's gold foil experiment?
Ans. The key finding of Rutherford's gold foil experiment was that most of the alpha particles passed through the gold foil, indicating that atoms are mostly empty space with a dense nucleus at the center.
4. How did Rutherford's model differ from Thomson's model?
Ans. Rutherford's model proposed that atoms have a small, dense, positively charged nucleus at the center, while Thomson's model suggested that electrons were distributed throughout a positively charged sphere.
5. What is the significance of the Thomson and Rutherford atomic models in the development of atomic theory?
Ans. The Thomson and Rutherford atomic models played a crucial role in shaping our understanding of atomic structure. Thomson's model introduced the idea of subatomic particles, while Rutherford's model led to the discovery of the atomic nucleus and the concept of a planetary model of the atom.
