Why was J.J Thomson's discovery an important step in the development of the atomic theory?
J.J. Thomson's discovery of the electron in 1897 was crucial in the development of the atomic theory because it showed that atoms were not indivisible, as previously believed. Instead, atoms were composed of smaller subatomic particles, revolutionizing the understanding of atomic structure and paving the way for the later models of the atom.
What else can I help you with?
Why did a lot of time go by between Thomsons work and Daltons?
The gap between Thomson's work on the electron and Dalton's work on atomic theory can be attributed to advancements in experimental techniques and theoretical understanding. Thomson's discovery of the electron in the late 19th century provided the foundation for understanding the subatomic world, which set the stage for Dalton's work on atomic theory in the early 19th century. Additionally, the development of chemistry as a science and the accumulation of experimental evidence over time allowed for a more comprehensive understanding of atomic structure and behavior.
What is the contribution of ernest Rutherford in development of atomic theory?
Ernest Rutherford is known for his famous gold foil experiment, which led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. His work helped to refine the understanding of the structure of the atom and laid the foundation for the development of modern atomic theory.
What is the contribution in physics of James chadwick?
James Chadwick's most significant contribution to physics was his discovery of the neutron in 1932, which helped to further our understanding of atomic structure and led to the development of nuclear physics.
