It is similar to a solar system. The sun is the nucleus with protons and neutrons and the electrons are the planets.
The planetary model of an atom is simple. The nucleus is the planet and the electrons are the moons in the model.
Today the accepted atomic model is quantic.
a nucleus in an electron cloud.
The model used to describe the behavior of very small particles like electrons orbiting an atom is the quantum mechanical model. This model incorporates principles of quantum mechanics to describe the probability of finding an electron at different locations around the nucleus of an atom.

Yes, the shell model is a physical model used in nuclear physics to describe the structure of atomic nuclei. It is based on the idea that nucleons (protons and neutrons) occupy energy levels or "shells" within the nucleus, similar to the electron shells in an atom. The shell model helps explain certain nuclear properties and phenomena.
the atom as a tiny, dense, positively charged core called a nucleus

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.
Thomson's model does not account for the existence of positively charged particles within the atom. It also does not explain the stability of the atom or the arrangement of electrons within the atom. Additionally, it fails to describe the presence of different energy levels in the atom.
The Bohr model for hydrogen is a proton orbited by an electron.
