In the Geiger–Marsden alpha particle scattering experiment, a beam of alpha particles was directed at a thin gold foil. Two main observations were made:
Which of the following correctly matches these observations to the conclusions drawn about atomic structure?
Observation 1: The positive charge is spread uniformly throughout the atom. Observation 2: The atom consists mostly of empty space.
Observation 1: The atom consists mostly of empty space. Observation 2: The positive charge and most of the mass of the atom are concentrated in a tiny, dense nucleus.
Observation 1: Electrons are arranged in discrete, stable energy levels. Observation 2: The atom behaves as an indivisible, solid sphere.
Observation 1: The positive charge and most of the mass of the atom are concentrated in a tiny, dense nucleus. Observation 2: The atom consists mostly of empty space.
