The Strong Force.
nuclear force
Protons and neutrons are not elementary particles. They're made of particles called quarks (which we're reasonably sure areelementary particles). These quarks are held together in hadrons such as protons and neutrons by something called the color force, also known as the strong nuclear force.The residual color force, which you can sort of think of as "left over" from holding the individual protons and neutrons together, holds the collection of protons and neutrons together in the nucleus.
Nuclear Fusion. This process involves 'fusing' together two smaller nuclei to form a bigger nucleus.
There are four fundamental forces in particle physics: electromagnetism, gravity, the strong nuclear force, and the weak nuclear force. The strong nuclear force is mediated by a particle called the gluon (like electromagnetism is mediated by the photon). Protons and neutrons are not elementary particles. They are composed of two types of quarks, up and down, with charges of +2/3 and -1/3 respectively. Quarks are bound to eachother by electromagnetism but, more importantly, also by the strong nuclear force. So the strong nuclear force is responsible for holding together the protons and neutrons themselves. The gluons then bind protons and neutrons together indirectly through exchanging composite particles called pions, made of two quarks held together by gluons.
It not really a force, atoms are made up of protons, neutrons and electrons. The outside bit of atoms is the electrons bit which is fuzzy and when the atoms touch each other the fuzzy bits sort of join together. The weak nuclear force holds atoms together in a compound and the strong nuclear force holds atomic particles together within the atom. They are called Electromagnetic forces.
The Strong nuclear force is what holds the protons and neutrons together in an atoms nucleus. Think of a gorilla with an atom of two protons and two neutrons together and his hands holding the atoms together.
Fallout.
On the contrary, the main force in the nucleus keeps particles together. This is called the strong nuclear force, and it keeps similarly charged protons together, overcoming the electrostatic
Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
The nuclear reaction when atoms split is called fission. Fission is where atoms split into smaller particles or atoms.
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 rock formed when particles stick together is called Sedimentary Rock. The type of this rock depends on the composition and texture of the particles sticking together.
