What hold particles together?
- strong nuclear force
- weak nuclear force
- molecular binding energy
- electrostatic force
- magnetic force
When the attractive forces holding particles together are strong enough to hold them together as a group but not as a fixed position they form a what?
What other particle is found in the nucleus and separates protons so that the strong force can hold the nucleus together?
It appears that you have some confusion about the particle physics inside the nucleus. Nothing "separates protons so that the strong force can hold the nucleus together", the strong force acts via the exchange of particles called mesons. The atomic nucleus contains particles called protons and neutrons. The strong force binds the protons and neutrons together via the exchange of particles called mesons between those protons and neutrons.
Because only the particles are packed together like that the solid can have define shape and volume. If they not packed together that are liquid.So we can use this point (the particles are packed together) to know what is that? Solid, Liquid or Gas. ---- The particles of a solid are packed tightly together, the particles of a liquid can move around but are still touching each other, and the particles in a gas are…
Under the influence of external pressure the particles are forced together. Under the particles' own gravitational force the particles come together. Technically speaking there must be an external force to bring the particles of matter together. Another point to be noted is that when the particles moves so close to together that it crosses its critical mass a black hole is developed. But not always.
