He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.
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.
Ernest Rutherford was the first scientist to describe an atomic model in which most of the atom is empty space. His model proposed that atoms have a dense positive nucleus surrounded by orbiting electrons in empty space.
Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. He demonstrated that atoms are mostly empty space with a dense, positively charged nucleus at the center. This helped pave the way for further understanding of atomic structure and the development of the modern atomic theory.
He completely changed the atomic model of his time to something that is quite similar to the current model of the atom. His "alpha scattering experiment" provided the evidence that the atom was mainly empty space, and that most of its mass and all of its positive charge was located in a small, dense core(now called the nucleus).
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
Ernest Rutherford created the nuclear model of an atom!
Ernest Rutherford is known for his famous gold foil experiment, which led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. His work helped to refine the understanding of the structure of the atom and laid the foundation for the development of modern atomic theory.
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.
John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.
The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.
its was Ernest Rutherford who proposed the planetary atomic model

In 1911, Rutherford proposed a new model for the atom. His experiments were the first to show that the atom must consist of a very tiny positively charged nucleus surrounded by negatively charged electrons. (For the record, Rutherford also discovered and named alpha, beta and gamma radiation.)

Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus. This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.
