Hint: We know that Rutherford did the gold foil experiment. In his experiment, he noticed that several of the alpha particles went through the foil. Certain of the positively charged particles were deflected back at angles that very large and some of the alpha particles were reflected back by ${\text{18}}{{\text{0}}^{\text{o}}}{\text{.}}$

Now we can discuss about the Rutherford Model of Atom,
Rutherford did the gold foil analysis, which caused him to infer that the core of the molecule contains the greater part of the nuclear mass. He saw that,
Most of the alpha particles went through the foil.
Few of the emphatically charged particles were redirected at enormous points.
Few of the particles were reflected back by ${\text{18}}{{\text{0}}^{\text{o}}}{\text{.}}$
Conclusion of Rutherford’s Gold Foil experiment:
The core of the molecule contains the vast majority of the nuclear mass.
The core of the particle is positively charged.
The particle comprises for the most part void space.
As per Rutherford model of atoms,
A molecule includes decidedly charged particles and the mass of an atom is packed in a little area called the nucleus. It was subsequently found that the core comprises protons and neutrons.
The nucleus of atoms is encircled by regrettable charged particles called electrons and these electrons rotate around the nucleus in different discrete energy levels called as orbitals.
The net charge on a molecule is zero or electrically unbiased in light of the fact that electrons are contrarily charged particles and the nucleus is emphatically charged. The core and electrons are held together by solid electrostatic power of attractions.
The size of the core is little when contrasted with the total size of an atom.
Rutherford's model of atom expressed that the positive matter is amassed in the central region of the particle called the nucleus. A nucleus of a molecule is little, thick and heavy that contains protons (positive charge) and neutrons (no charge).
The portion of the atom which was discovered by Rutherford’s alpha particle scattering experiment is the nucleus.

Note:
We need to remember that the Rutherford model of an atom came to existence when experiments of J.J Thomson failed to explain the results that were related to the atomic structure of elements. We have to know that the modified version of Rutherford’s model of an atom is Bohr’s atomic model. One of the major drawbacks of the Rutherford model is that the stability of an atom could not be explained.
