WebThe 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. WebApr 15, 2024 · Heavy metal pollution is a global problem affecting the environment and human health. Sediment is the source sink of heavy metals in water.
