Protons and neutrons.
There're two particles in the atom nucleus (protons and neutrons)
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
The two particles that make up the nucleus of an atom are the proton and the neutron. The proton has a positive charge, and the neutron doesn't have a charge.
The center of an atom is made up of two particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no charge. Together, they make up the nucleus of an atom.

Protons and neutrons compose the nucleus of an atom. Most of the mass of an atom exists in the nucleus. Other smaller sub atomic particles such as quarks exist, but are usually not addressed until advanced physics or chemistry classes.
The particles of the atom in the nucleus are the protons and neutrons. Protons carry a positive charge and neutrons have no charge. These two make up the vast majority of an atom's mass. Electrons, with their negative charges, orbit the nucleus in different energy levels.
The neutral particles found in the nucleus on an atom are called neutrons. Positive particles found in the nucleus are protons.
The nucleus of a helium atom is composed of protons and neutrons. Specifically, a helium nucleus contains two protons and typically two neutrons. Electrons, which are also part of the atom, orbit the nucleus but are not found within it.
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
