Atoms are divisible.
These hypotheses are not valid today.
dalton was wrong about atoms being indivisible. atoms are divisible into several subatomic particles. dalton was wrong about all atoms of a given element having identical properties.
Dalton came up with that theory. It was proven wrong, though.
Daltons said All elements are made up of atomsAtomos are indivisible and indistructableAtoms of a given element are identical in mass and in all other propertiesA compound is formed when the atoms of two or more elements combine
John Dalton
John Dalton believed that all elements are made of atoms and that atoms are identical if they are of the same element. He is the first one to have combined substances to make new substances through chemical reactions.
Because the existence of isotopes was discovered not all atoms of an element are identical.
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.

The atom. Considered by Dalton to be indivisible and indestructible.
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
In his time were not known the isotopes and Dalton supposed that all atoms of a chemical element are identical.

Dalton
He said that atoms cannot be destroyed nor created, and atoms are indivisible but now the scientists can break atoms into parts so now they are no more indivisible. So the last law of Dalton's Atomic Theory have been modified.
