What is Daltons Greek model?
John Dalton is best known for work on atomic theory. While his models were very similar to the speculation of the Greeks made centuries before, his theory differentiated in the idea that chemical combination takes place between particles of different weights.
Who is model of the atom has no subatomic particles?
The model of the atom with no subatomic particles is the Dalton model, proposed by John Dalton in the early 19th century. In this model, atoms were considered indivisible and the smallest building blocks of matter. Subatomic particles like protons, neutrons, and electrons were not discovered until much later.
What discovery lead the scientists to question john daltons model of the atom and to favor jj Thomsons model?
The discovery of the electron by J.J. Thomson through his cathode ray tube experiment led scientists to question John Dalton's model of the atom. Thomson's observation of negatively charged particles in the cathode ray, along with their behavior under electric and magnetic fields, contradicted Dalton's indivisible and uniformly dense model of the atom. Thomson's model, proposing that atoms contain subatomic particles (electrons), gained favor due to its ability to explain these experimental findings.
Who was the scientist who developed the atomic theory of matter?
The scientist who developed the atomic theory of matter was John Dalton. He proposed that matter is made up of indivisible particles called atoms that combine in specific ratios to form different compounds.
Which scientists law about the ratios of masses of elements in a compound did John Daltons work on the atomic structure help to explain?
John Dalton's work on atomic structure helped to explain the Law of Multiple Proportions put forth by French chemist Joseph Proust. This law states that when elements combine to form compounds, they do so in simple whole-number ratios based on their atomic masses. Dalton's atomic theory proposed that elements are made up of indivisible particles called atoms, which provided a conceptual foundation for understanding how elements combine to form compounds in fixed ratios.
When was john daltons atomic model billliard model made?
see along time ago before dinosaurs walked the earth. the end.
Why was daltons model of the atom changed after Thompson experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within

How did thomsons atomic model differ from daltons model?
If i remember correctly, Dalton's focuses more on the nucleus while Thompson's focuses more on electrons. But I'm not sure. well in 1803 John Dalton makes a strong case that atoms are small, solid balls and Joeseph John Thompson discovers electrons, and developed plum pudding model of an atom..... Dalton says that nothings smaller than the atom, but Thompson says that electrons are.
John daltons inventions?
John Dalton was a British scientist known for his work in chemistry and the development of atomic theory. His most notable invention was the concept of atomic theory, which proposed that all matter is composed of tiny, indivisible particles called atoms. Dalton also introduced symbols to represent elements and their atomic weights, laying the foundation for modern chemistry.
What experiment did daltons use for his atomic theory?
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.

What where Daltons experiments?
John Dalton was concerned by the problems of color blindness, meteorology, measurement of altitude, gas laws, atomic weights, structure of the matter, etc.
Where did john Dalton create his atomic model?
1956
Which event would be impossible to explain by using John Daltons model of the atom?
A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
What is John Dalton's scientific attitude?
