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 part of daltons atomic theory was proved incorrect?
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.
Daltons atomic therory?
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
When did Democritus make his first discovery?
Democritus is known for his atomic theory, which he developed in the 5th century BC. His ideas were revolutionary for the time and laid the groundwork for modern atomic theory.
Who is the Irish chemist who put forward the modern atomic theory?
The Irish chemist who proposed the modern atomic theory is John Dalton. He introduced this theory in the early 19th century, which states that all matter is composed of tiny, indivisible particles called atoms.
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.
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.
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.
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.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Who proposed the first modern atomic theory?
The first modern atomic theory was proposed by John Dalton in the early 19th century. Dalton's theory stated that all matter is made up of tiny, indivisible particles called atoms, and that atoms of different elements have different masses and properties.
Why was daltons model accepted?
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
What was Lavoisier's contributions to the development of the modern atomic theory?
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
In what way does Dalton's theory differ from modern atomic theory?
he was wrong
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.
Did postulate 4 of Daltons atomic theory holds true now?
No, postulate 4 of Dalton's atomic theory, which stated that atoms of the same element are identical, is not entirely true. We now know that isotopes exist, which are atoms of the same element with different numbers of neutrons. This means that atoms of the same element can have slightly different masses.
