WebbThe modern atomic theory, proposed about 1803 by the English chemist John Dalton ( Figure 2.2 "John Dalton"), is a fundamental concept that states that all elements are composed of atoms. In Chapter 1 "Chemistry, Matter, and Measurement", we defined an atom as the smallest part of an element that maintains the identity of that element. WebbThe Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced this after measuring how an alpha particle beam is scattered when it strikes a thin metal foil.
