Part B. On the basis of Rutherford’s experimental observations, which of the following statements describes the structure of the atom according to Rutherford's atomic model?
In an atom, positively charged particles are dispersed in the space surrounding the negatively charged sphere.
In an atom, the positive charges are located in a small core within the atom called the nucleus.
In an atom, all of the positive and negative charges are randomly distributed.
In an atom, negatively charged electrons are dispersed in the space surrounding the positively charged nucleus of an atom.
Check all that apply.
In 1909, Ernest Rutherford performed an experiment to explore the atomic structure. In his experiment, he projected high-speed α particles onto a thin gold foil. He found that all α particles did not follow the same path. Most of the particles passed through the foil without any scattering, implying that most of the space in an atom is empty. Some particles were scattered at a large angle, and very few of them scattered back in the direction from which they had come. Based on these observations, Rutherford proposed an atomic model, which is known as Rutherford’s atomic model.
