Protons and Neutons, I believe..
Because dont electrons revolve around the nucleus or something?
There're two particles in the atom nucleus (protons and neutrons)
The neutral particles found in the nucleus on an atom are called neutrons. Positive particles found in the nucleus are protons.
Protons and neutrons are the two atomic particles found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge and contribute to the mass of the nucleus.
Proton and neutron.
There are two particles in an atom's nucleus. The protons carry positive charge. The neutrons have no charge.
Assuming you mean the nucleus of an atom, the two particles found are protons and neutrons. Protons carry a positive charge (with a magnitude of +1 elementary charge), while neutrons carry no charge.
Neutrons and Protons are the two elementary particles found in the nucleus of an atom. Modern work shows that these are in turn made up of even more fundamental particles. These are further studied in Quantum Chromodynamics ("QCD").
Proton and neutron.
These particles are: protons, neutrons and electrons.
The latter two particles, the electron and the neutron, are found in the nucleus of an atom. The electron orbits the nucleus in the electron cloud, while the neutron is located alongside protons in the nucleus.
Electrons.
Nucleus (and it consists of protons and neutrons).
