its mostly empty space
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
The model atom Ernest Rutherford made is simply called the Rutherford Model. The experiment he conducted during his research is referred to as the Gold Foil Experiment. Rutherford is known as the father of nuclear physics.
The then current Plum Pudding theory of the atom was wrong: protons and electrons were not evenly distributed and free in the atom, instead the protons carrying the positive charge must be concentrated in a very small volume at the center of the atom that he named the nucleus with the electrons orbiting some distance away.
Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.
Earnest Rutherford

Ernest Rutherford concluded that an atom contains a very small, dense center, called a nucleus, with a positive charge as a result of his gold foil experiment.
He concluded that most of the mass of the mass of the atom is concentrated at a single place at the centre of atom. He named this place as the nucleus.
In Rutherford's gold foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positively charged center because most of the electrons passed through but a few were wildly deflected.
Rutherford supposed that the atomic nucleus is very small compared to whole atom.
Rutherford concluded that they have a nucleus,a central positive nucleus surrounded by negative orbiting electrons.
Cheese
It is called the "nuclear model" Rutherford concluded that 1. Atom is mostly empty space 2. Atom has a nucleus at its center 3. Electrons surround the nucleus
Rutherford's model for the atom, based on the Geiger-Marsden experiment results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the Atomic Mass of the atom. later this is called as nucleus.
Protons believe me
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
