Final answer:
Rutherford's model of the atom describes a tiny, dense, positively charged core called the nucleus, which contains most of the mass of the atom.
Step-by-step explanation:
Rutherford's model of the atom describes the atom as having a tiny, dense, positively charged core called the nucleus, which contains most of the mass of the atom. This means that statement D, "The electrons are located within the positive material of the nucleus," is the correct description of one feature of Rutherford's model of the atom.
