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.
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.
John Dalton. He put forward the atomic theory in 1808.
Atomic theory was founded by John Dalton. He proved this theory in 1803.
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
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.
john dalton developed the atomic theory , which he published in 1803
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
