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.
He gave the planetary model of atom. After studying the very famous alpha particle scattering experiment he introduced the model with negatively charged electrons going around the positively charged nucleus. But he could not explain about the stability of atom. Hence Bohr's atom model came in the scene.
Rutherford carried out the gold foil experiment, in which he was able to determine that an atom is mostly empty space, which explained why only some "charged particles" were deflected off the gold foil.
He carried out the gold foil experiment which allowed him to conclude that atoms are mostly made up of empty space.
The modern atomic model is elaborated by Niels Bohr.
He placed positive material in the atom's center.
its was Ernest Rutherford who proposed the planetary atomic model

Ernest Rutherford. Added: I would think Neils Bohr here. Clarification: I think it was Rutherford. Bohr's work came after the "Rutherford Model". There are many places to read about this, eg Wikipedia " Rutherford Model". Certainly Bohr refined the Rutherford Model even before his quantum ideas for the hydrogen atom. That's why the "planetary model" is sometimes called the "Rutherford-Bohr Model."

The modern atomic model is elaborated by Niels Bohr.
Ernest Rutherford created the nuclear model of an atom!
He placed positive material in the atom's center.
Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.

The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.

The atomic model that contained empty spaces within it was given by Mendeleev. The gaps were left for the elements that were not discovered at that time.
The ''plum pudding atomic model" is from J. J. Thomson, year 1904.
E. Rutherford developed his atomic model due to the results of his gold foil experiment. His atomic model describes a small central, dense core and a surrounding volume of charged particles.
In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.
