Detailed explanation-1: -Ernest Rutherford discovered the nucleus of the atom in 1911.

Detailed explanation-2: -Rutherford called the area of concentrated positive charge the nucleus. He predicted-and soon discovered-that the nucleus contains positively charged particles, which he named protons.

Detailed explanation-3: -Rutherford’s explanation, which he published in May 1911, was that the scattering was caused by a hard, dense core at the center of the atom–the nucleus.

Detailed explanation-4: -Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Detailed explanation-5: -The vast majority of the volume of an atom is therefore empty space. Shortly after the World War I, in 1920, Rutherford proposed the name proton for the positively charged particles in the nucleus of an atom.
