FAQs on Thomson's Atomic Model Video Lecture - Chemistry Class 11 - NEET

1. What is Thomson's atomic model?
Ans. Thomson's atomic model, also known as the plum pudding model, was proposed by J.J. Thomson in 1904. According to this model, atoms are composed of a positively charged sphere with negatively charged electrons embedded within it, much like plums in a pudding.
2. What is the significance of Thomson's atomic model?
Ans. Thomson's atomic model was significant as it provided the first evidence for the existence of subatomic particles. It challenged the prevailing notion of the indivisibility of atoms and laid the foundation for further research on atomic structure.
3. How did Thomson propose his atomic model?
Ans. Thomson proposed his atomic model based on his experiments with cathode rays. He observed that these rays were deflected by electric and magnetic fields, indicating the presence of negatively charged particles within atoms. This led him to propose the plum pudding model to explain the structure of atoms.
4. What are the limitations of Thomson's atomic model?
Ans. Although Thomson's atomic model was groundbreaking, it had certain limitations. It did not explain the distribution of positive charge within the atom, the stability of atoms, or the nature of the nucleus. It also failed to account for the existence of different elements with varying properties.
5. How did Thomson's atomic model contribute to the development of atomic theory?
Ans. Thomson's atomic model was a crucial step in the development of atomic theory. It paved the way for the subsequent discoveries of the nucleus by Rutherford and the quantum model by Bohr. It provided a starting point for scientists to further explore the structure of atoms and the behavior of subatomic particles.
