How did rutherfords's experimental evidence lead to the development of a atomic model?
Rutherfords gold foil experiment demonstrated the existence of the nucleus and lead to the model of a positive nucleus surrounded by electrons. This model was further developed by Bohr and then by Schroedinger and others to become the quantum mechanical model we now have with electrons in orbitals around the central positively charged nucleus..
What else can I help you with?
Who is credited with the first atomic theory based on expiramental evidence?
scientific method used in the development of atomic theory
Bohr found experimental evidence for his atomic model by studying?
The electron cloud
What scientist did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.
Who revived the atomic theory and put on a solid experimental foundation in about 1803 by?
John Dalton revived the atomic theory in 1803 by proposing that elements were made up of tiny, indivisible particles called atoms. He also outlined basic principles of atomic theory and provided experimental evidence to support his ideas.
What were arthur compton's contributions to the atomic theory?
Arthur Compton made significant contributions to the atomic theory by discovering the Compton effect, which provided experimental evidence for the particle nature of light. This discovery helped establish the understanding that light can behave as both a wave and a particle, which was fundamental to the development of quantum mechanics.
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.
Why the ideas of Democritus were not useful in a scientific sense?
Democritus' ideas were not useful in a scientific sense at the time because they were not supported by empirical evidence and lacked experimental verification. Additionally, his atomic theory was an abstract concept that was not mathematically or experimentally testable with the technology available in his era. It wasn't until much later, with advancements in technology and the development of modern physics, that atomic theory was revisited and eventually validated.
The contribution of Galileo Galilie in development of atomic theory?
I think it was that he theorized that when a new substance is made, the elemnts didn't change the atoms just rearranged. I'm not certain though. Galileo is more known for his research on planets.
What did Philipp Lenard Contribute to the atomic theory?
Philipp Lenard made contributions to understanding the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1905. However, he did not contribute significantly to the development of the atomic theory. His work focused more on experimental physics and electron behavior rather than atomic structure.
How did Rutherford experimental evidence lead to the development of new atomic model?
Rutherfords gold foil experiment demonstrated the existence of the nucleus and lead to the model of a positive nucleus surrounded by electrons. This model was further developed by Bohr and then by Schroedinger and others to become the quantum mechanical model we now have with electrons in orbitals around the central positively charged nucleus..
Although Dalton's atomic theory was rejected at first he used his theory to do what that soon resulted in his theory being accepted by scientists?
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
What did Charles augustin de coulomb contrubite to the atomic theory?
Charles-Augustin de Coulomb contributed to the development of atomic theory by conducting experiments that established the law of electrostatic attraction and repulsion between charged particles. His work provided evidence for the existence of discrete charged particles, which was a fundamental concept in the development of atomic theory.
