He described the mass of an atom was located in a single point not equally shared as the plumb pudding model suggested it. However he did not use the term nucleus in his report.
You think probable to Ernest Rutherford.
Ernest Rutherford's model of the atom disproved the Plum Pudding Model proposed by J.J. Thomson. Rutherford's gold foil experiment led to the conclusion that the atom is mostly empty space with a small, dense nucleus at the center, which contradicted the idea of electrons being randomly distributed throughout the atom.

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.
This was an idea of Ernest Rutherford (1871-1937) from 1911.
Ernest Rutherford created the nuclear model of an atom!
its was Ernest Rutherford who proposed the planetary atomic model
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.
Ernest Rutherford is credited with the development of the "Rutherford Model" of the atom, which proposed that the atom consisted of a small, dense nucleus containing positively charged protons orbited by negatively charged electrons. This model was developed in 1911 based on experiments conducted in his laboratory.
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.
You think probable to Ernest Rutherford.
Ernest Rutherford's 1911 model of the atom failed to explain why electrons, which are negatively charged, do not collapse into the positively charged nucleus due to electrostatic forces. This model was unable to account for the stability of the atom.
Ernest Rutherford's model of the atom disproved the Plum Pudding Model proposed by J.J. Thomson. Rutherford's gold foil experiment led to the conclusion that the atom is mostly empty space with a small, dense nucleus at the center, which contradicted the idea of electrons being randomly distributed throughout the atom.
Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.
Ernest Rutherford
Ernest Rutherford is the scientist who envisioned the atom as a ball of positive charge with electrons embedded in it. This model became known as the Rutherford model of the atom.
