Atomic Theory Questions & Answers Democritus - Answer-Proposed concept of atoms without experimental evidence John Dalton - Answer-Developed atomic theory based on experimental evidence Dalton's Atomic Theory - Answer-Elements made of indivisible atoms, atoms rearrange in chemical reactions, compounds form in simple ratios Aristotle - Answer-Denied atomic theory, argued for continuous, non-divisible matter Errors in Dalton's Atomic Theory - Answer-Atoms are divisible, not all atoms of a...

Why are alpha particles deflected by the nucleus? - Answer-Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." - Answer-False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic particles? - Answer-The nature of the electron is i...
