Dalton is credited with the original atomic theory. He thought atoms were 'indivisible' and had no smaller parts.
Thompsom discovered the electron, but hand no idea of atomic structure, and his theory was called the 'plum pedding' model of the atom. There was some positive thick fluid that the electrons were stuck in. His experiments knoched out electrons, but he could not knock out positive particles, so he thought there were none.
Rutherford supervised and helped two grad, students with what is referred to as the gold foil experiment. He took the results of the experiments and mathematically analyzed them to find theat there was a very heavy, positively charged, very small central part of the atom. He called it the nucleus. So he is credited with the discovery of the nucleus, which changed atomic theory again to say that there is a heavy positively charge nucleus in the atom. But he still didn't know the relationship of the nucleus and the electron.
Later Bohr came up with a theory of electrons in exact orbits, like planets orbiting the sun. Even later, more scientists changed this theory.

John Dalton's atomic theory stated that atoms of the same?
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
Who discovered all things are made of atoms?
In my textbook it sayes that actually Dalton believed that all substances are made of atoms, and this was part of his atomic theory, which he published in 1803.
Why is John Dalton's atomic theory still mentioned in science?
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
