How can an stm help improve daltons theory?
An STM (scanning tunneling microscope) can help improve Dalton's atomic theory by providing visual evidence of individual atoms and their arrangements on surfaces. This experimental data can offer insights into the precise structure and behavior of atoms, supporting or refining Dalton's ideas based on empirical observation. Additionally, STM allows for the direct observation of atomic interactions and bonding, which can lead to a deeper understanding of atomic behavior beyond what Dalton's theory originally proposed.
Who opposed J J Thomsons atomic theory?
Some scientists who opposed J.J. Thomson's atomic theory included William Prout, Ernst Rutherford, and Max Planck. These scientists challenged aspects of Thomson's model, such as the presence of subatomic particles within the atom.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
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.
What was one main point if daltons atomic theory?
One main point of Dalton's atomic theory was that all matter is made up of tiny, indivisible particles called atoms. He also proposed that atoms of the same element are identical in size, mass, and other properties, while atoms of different elements have different sizes and weights.
What aspect of Dalton's theory was supported by Thomsons findings?
the electron part
What aspect of Dalton's theory was not supported by Thomsons findings?
Dalton's theory proposed that atoms are indivisible and have no subatomic particles, which was not supported by Thomson's discovery of the electron. Thomson's findings showed that atoms contain subatomic particles, challenging the notion of indivisible atoms in Dalton's theory.
How does Daltons atomic theory explain the law of definite proportions?

Why scientists accepted daltons atomic theory but not the idea of an atom proposed by the Greek philosopher?
the Greek Philosophers did not test their theory.
How was Thomsons atomic theory different from Rutherfords atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
What part of daltons theory was modified after discovery of isotopes?
Atoms may not be changed into other atoms.
What part of daltons theory was modified after the discovery of isotope?
Atoms may not be changed into other atoms.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
What did daltons theory say about protons and electrons?
Nothing,Dolton did not know about Protons,neutrons and electrons
The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.
How did daltons atomic theory lead to the different model scientists have today?
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
Why was Darwins theory not accepted?
Darwin's theory was accepted,at first Darwin himself did not publish his findings as he did not feel anybody else would agree with his findings but once he found that a fellow scientist had conducted the same research and was going to publish his findings Darwin then also decided that he would publish his findings also.
