Mark the statement as true or false.All of the proposed ideas by Dalton, Thomson, and Rutherford are still used in the Modern Theory of the Atom.

False. Modern atomic theory retains some ideas from Dalton, Thomson, and Rutherford, such as matter being made of atoms and atoms having electrons and a small, dense nucleus. But other parts were replaced: atoms are divisible, and Thomson’s plum-pudding model is not the modern model. So not all of their proposed ideas are still used.
