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...
