A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
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.
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.
John Dalton held many roles within his lifetime. He was a chemist, meteorologists, and physicist. He affected the world through his development of the atomic theory and by providing feedback on his research conducted for color blindness.
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
JJ Thomson's discovery of electrons indicated that atoms were not indivisible.

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
protons,neutrons and electrons are the sub atomic particles
see along time ago before dinosaurs walked the earth. the end.
1) elements are composed of atoms 2) atoms of same elements = 3) atoms of different elements not = 4) atoms fomr compounds in definite ratios H2O

what is john daltons scientific attitude
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
Carbon
he worked at the circus as a proffesional clown
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.
