There was a huge evolution as to understanding what an atom was and there were many scientists who helped to make this happen. The first scientist was Democritus‚ he lived from 460 BC to 370 BC. His main theories were that everything is made up of atoms‚ atoms cannot be divided‚ and atoms are small and solid particles. He named the atom “atomos” it was greek word and it means “not able to be divided.” The next scientist who worked with atoms was John Dalton‚ he lived from 1766 to 1844. His main theories

Which of the following statements is part of Democritus’s theory about atoms? a. Atoms are the smallest piece of matter. 3. We know that Democritus was right about atoms. So why did people ignore Democritus’s ideas for such a long time? Democritus’s ideas were ignored for a long time because he had no proof of the atoms existence.

Ernest Rutherford’s experiment was that he took a piece of gold foil and shot helium atoms at it. In theory they should have rebounded off of the gold foil because scientists at that time believed that the atom was a solid sphere‚ but what actually happened was that most of the atoms went through the gold foil.This showed that the atom wasn’t just a solid sphere like they believed but actually had a nucleus with electrons surrounding it. In 1897‚ a British physicist named J. J. Thomson discovered
