The nuclear model of the atom was proposed by Ernest Rutherford in 1911. This model suggested that an atom has a small, dense nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in empty space.
Rutherford discovered the atomic nucleus, proposed a nuclear model of the atom also he isolated nitrogen.
Ernest Rutherford is credited with mapping the atom through his famous gold foil experiment in 1909. He discovered the nucleus of the atom, which led to the development of the nuclear model of the atom.
Rutherford pictured the atom as a dense positively charged nucleus at the center, surrounded by orbiting negatively charged electrons. This model, known as the nuclear model, revolutionized our understanding of the structure of the atom.
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.
Rutherford presented the nuclear model of atom first.
Ernest Rutherford created the nuclear model of an atom!
The nuclear atom differs from the uniform sphere model, because they both are made from different atoms because of the elements.

British Physicist Ernest Rutherford is considered the 'father of nuclear physics' and is credited with splitting the first atom in 1917. He pioneered the Rutherford model of the atom and theorized that the charge of an atom is concentrated into a nucleus. He was able to split the atom in a nuclear reaction between alpha and nitrogen particles which led to the discovery of the proton.
The nuclear model of the atom suggests that an atom is mostly empty space with a small, dense nucleus at the center. The volume of an atom is therefore primarily occupied by this empty space, with the nucleus accounting for a very small portion of the total volume.
The "plum pudding" (as they called it) model suggest's that the electrons were dispersed throughout the atom. Where as the nuclear model has positively charged protons which are present in the center of an atom (called the nucleus)
The nuclear model shows that an atom has a small, dense nucleus at its center made up of protons and neutrons, with electrons orbiting around it in specific energy levels. This model explains the overall structure of an atom and how its subatomic particles are arranged.
