John Dalton's atomic model, proposed in the early 19th century, depicted atoms as indivisible and solid spheres, akin to tiny balls. He suggested that each element consists of identical atoms that differ from those of other elements, and that chemical reactions involve the rearrangement of these atoms. Dalton's model laid the groundwork for modern chemistry by introducing the concept of atoms as fundamental building blocks of matter and establishing the idea of atomic masses for different elements. However, later discoveries revealed that atoms are not indivisible and contain subatomic particles.
What else can I help you with?
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.
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.
Which describes john daltons observation of elements in any given compound?
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.
What is a component of John Daltons atomic theory?
One key component of John Dalton's atomic theory is the idea that matter is composed of indivisible particles called atoms. Dalton proposed that all atoms of a given element are identical in mass and properties, and that atoms combine in simple whole-number ratios to form compounds. This theory laid the groundwork for modern chemistry by introducing the concept of the atomic nature of matter.
What was john daltons four postulates of the tomic heory?
John Dalton's atomic theory consists of four key postulates: First, all matter is made up of indivisible particles called atoms. Second, atoms of the same element are identical in mass and properties, while atoms of different elements differ. Third, atoms combine in simple whole-number ratios to form compounds. Finally, during a chemical reaction, atoms are rearranged but not created or destroyed, maintaining their identity throughout the process.
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 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.
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

What was john daltons contribution to the atomic theory?
He said that atoms can not be divided; in one matter all the atoms are of same kind,same mass and same type. He also said that different matters have different kinds of atoms. He furthermore said that atoms from different matters meet together at a particular rate and make molecules.
