That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.

Which of Dalton's atomic theory is not supported?
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
What part of Daltons atomic theory was then proven to be incorrect?
Two principles not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
How did Thomson experiment change Dalton atomic model?
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
Is an element composed of millions of identical atoms?
Yes, an element is composed of millions of identical atoms.
What kind of information might be available to scientists today that would lead them to disagree with Dalton's atomic theory?
1. Discovery of isotopes: not all atoms of the same chemical element are identical. 2. Discovery of the atomic structure: atoms are indivisible by chemical methods but they are divisible with physical methods in components.
The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.
Which parts of Daltons theory were later found to be erroneous?
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 hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that?
Because the existence of isotopes was discovered not all atoms of an element are identical.
Which part of daltons atomic theory are known to be incorrect?
The idea that atoms are indivisible and indestructible, and the idea that all atoms of the same element have the same mass.
Which of Dalton's atomic theory is not supported?
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
Dalton hypothesized that atoms are indivisible and that all atoms of an element are identical. It is now known that .?
Atoms are divisible.
What is the modification of John Dalton's atomic theory?
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
The weight in daltons of one atom of an element is?
density
What is the smallest indivisible particle of an element?
It is an atom.
What part of Daltons atomic theory was then proven to be incorrect?
Two principles not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
Which of Jhon Daltons statements about the atom was proven false because of the discovery of isotopes?
Dalton said that all atoms of one element are identical. they are chemically identical but not identical in mass. he did not know of isotopes, which are chemically identical atoms with different numbers of neutral neutrons. ex: all carbon atoms act the same chemically but some mass at 12, others at 14.
What was Daltons theory based on?
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
