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. !
