Assuming you are talking about an atom, which you really should have stated in your question, the nucleus (the "central part" of the atom) consists of neutrons and protons. The particles orbiting the nucleus are electrons.
Protons and neutrons form the nucleusof the atom with electons orbiting it
By Halos I believe you mean rings. The rings are actually millions of pieces of rock and ice orbiting a planet, similar to the two asteroid belts orbiting the sun. Everybody knows Saturn's rings, but Jupiter, Neptune and Uranus also have ring systems.
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.
All magnetism is due to circulating electric currents. In magnetic materials the magnetism is produced by electrons orbiting within the atoms; In most substances the magnetic effects of different electrons cancel each other out, but in some, such as iron, a net magnetic field can be induced by aligning the atoms.

Neutrons are microscopic particles fount in the nucleus of atoms. Electrons are particles orbiting the nucleus.
Imagine a hydrogen atom with one orbiting electron. The electron that is orbiting would generate two magnetic fields. One caused by its rotation, and the other caused by its spin.
Electrons, my confused compadre. Electrons.
The general particles of an atom are Protons, Neutrons and Electrons. The Protons and Neutrons are in the Nucleus of the atom and the Electrons are orbiting the Nucleus.
At the core of an atom, is a mass of protons and neutrons. Orbiting the core, are the electrons.
The electrons.The electrons.The electrons.The electrons.
Electrons are negatively charged particles of atoms. They are found orbiting the nucleaus at a high speed.
It appeared from flattened disk of gas and/or dust orbiting the sun.
