The proton has a positive charge, +1.
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
The Rutherford atomic model contain a central, positive, concentrated mass called atomic nucleus; around the nucleus are moving electrons.
According to the atomic model, protons and neutrons are found in the nucleus at the center of the atom. Electrons, on the other hand, are located in orbitals surrounding the nucleus. This organization distinguishes the positive charge and mass concentrated in the nucleus from the negative charge of the electrons in the outer regions.

The proton has a positive charge, +1.
The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.
The main feature of Thomson's atomic model that was changed after Rutherford's discoveries was the location of the positive charge in the atom. Rutherford discovered that the positive charge was concentrated in a small nucleus at the center of the atom, rather than being spread out evenly throughout the atom as Thomson had proposed.

Early Models of the Atom knew about the electrons, but not, where the positive charge is located.Rutherford Experimented by bombarding α-particles (positively charged) on a thin metal foil and observed, that some α-particles are scattered to backward angles, it showed that there is an atomic nucleus, which is heavier than the α-particles.Rutherford suggest a model in which The Atom consists of an atomic nucleus with positive charge concentrated in the center, surrounded by electrons. It looks a lot like a mini- solar system.
The plum pudding model by JJ Thomson.
Rutherford's model of the atom consisted of a positively charged center, known as NUCLEUS, which also contained most of the atom's mass. Around the nucleus orbited the negatively charged electrons.
...a positive charge. He called these central regions the nucleus. This model laid the foundation for the modern understanding of atomic structure.
He described the atom as a sea of positive charge sprinkled with electrons
