Me with atoms and dalton i beg you which of the following statements is false about dalton's atomic theory? 1. scientists later improved parts of dalton's atomic theory. 2. parts of the theory are no longer accepted as correct. 3. it was the first theory to propose that matter was made of tiny indestructible pieces of matter. 4. it was based on experimental evidence provided from leading scientists of that time. i think that the answer is either 3, because wouldn't democritus be the first person to propose tiny indestructible pieces of matter? or 4, because i don't think there were machines available to be able to test his theory with experiments. !

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.

Dalton based his theory on the law of conservation of mass and the law of constant composition.

The first part of his theory states that all matter is made of atoms, which are indivisible.

The second part of the theory says all atoms of a given element are identical in mass and properties.

The third part says compounds are combinations of two or more different types of atoms.

The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.
