(Doc. 1). They named their new idea ‘atomos’, meaning indivisible (OI). Sadly, their idea would be unsupported until 1803, when John Dalton published his atomic theory of matter. It stated that all matter was made of atoms, the atom is indivisible and indestructible, and that compounds are made up of two or more different kinds of atoms (OI). Years later, in 1911, Ernest Rutherford performed his gold-foil experiment and concluded that the atom has a positively charged nucleus and is mostly empty space (Doc 1, OI). This finding is almost the modern model, with the exception of the electron cloud (Doc.
