Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
Frederick Soddy demonstrated the existence of isotopes -- atoms of an element with different masses.
Dalton did not believe atoms can be subdivided; however, they can be in the transmutation of fission.
· All atoms of a given element are identical. · A given compound always has the same relative numbers of types of atoms.
Incorrect today:
· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.
John Dalton. He put forward the atomic theory in 1808.
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
The third principle of Dalton atomic theory is no supported.
yes it was Dalton's Theory
Atomic theory was founded by John Dalton. He proved this theory in 1803.

Dalton's Atomic Theory
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
john dalton developed the atomic theory , which he published in 1803
Dalton proposed it in Dalton's atomic theory (i think)
