This question has been at the centre of nuclear physics for many years. In the 30's when the subject began to be understood, it was postulated that there must be a force, that was not understood, but which overcomes the repulsion between similarly charged protons which you would normally expect, and also binds the uncharged neutrons into the nucleus. This came to be known as the Strong Nuclear Force. Work to try to establish what this force was and how it worked has been ongoing ever since. It is very short range and only effective inside the nucleus. It was gradually realised that what were thought to be fundamental particles, the proton and neutron, are not that at all, and there are many other particles involved, quarks, gluons, hadrons, among them. The subject is very complex, and scientists are still trying to explain it all, with the help of more energetic machines. The new one at CERN should give more data when it starts up. If you want to read more I can recommend in Wikipedia entries under Standard Model, Strong Interaction, and Nuclear Force, but warn it is hard stuff!
A force called the strong force holds protons and neutrons together in the nuclei of atoms.

(not a joke the force is actually called strong force)
Strong-force

this is wrong
subatonic particles
It varies from same as in a solid (glass, mercury), to that of a gas (and check out the "triple point") You should study - surface tension.
If we are just considering the "basic" nuclear reaction in a "regular" nuclear reactor, the particles of interest are the uranium-235 atoms (which are fissionable), and the neutrons, which get loose and cause fissions when they are absorbed by the U-235 atoms. We could broaden this to include some other reactions, but this is a fabulous place to begin to investigate nuclear physics.
Atoms are in a solid but as in particles it depends on the object.
when you push the plunger are the air particles closer together in the syringe or in the bubble
The protons and neutrons in the nucleus of an atom are held together by the strong force.
they are not held together.
The proton is one of the fundamental particles of the nucleus, the other is the neutron. The proton is positively charged, the neutron has no charge. They are held together by the strong nuclear force.
The particles within diamond are held together by the strong covalent bonds.
gas particles are not held together and in liquid sthey are not held very tightly.
By force of attraction.Depending on the atoms present, the force of attraction could be in the form of ionic bond, covalent bond, coordinate bond, hydrogen bond, van der Waals forces of interaction, dipole dipole interaction etc.
Yes, they are packed closely together
The largest force acting with in an atom is the van der wells force. It is several orders of magnitude stronger the the weak nuclear forces. It really depends on what sub atomic particles you are talking about.
the atom is held together by nuclear forces known as the electromagnetic force
Hideki Yukawa proposed the first theory of the strong force via meson exchange particles.
