What occurs when separated nucleons come together to form a nucleus?

When a pair of neutrons come together, you might not get much action. They may "collide" and scatter, but their neutral charge precludes much else. There is no "attracton" between them save the miniscule force of gravity. The literature does not speak to the n-n pair much except as a possibility suggested by Linus Pauling in the 60's. As the neutron is uncharged, there is no way to hold a pair together. Additionally, isospin constraints may actually prevent their getting together in the first place. It might be possible to do something odd. If we could get a pair of neutrons to fuse under certain circumstances, we might then get a beta decay to occur to change one of the neutrons into a proton, yielding deuterium, a heavy hydrogen nucleus. But that idea is straight out of dreamland. Proposals regarding n-n pairs still float in theoretical physics forums and the like, however, but they are almost universally coupled to discussion of a possible resonance state of an isotope where the pair exist as a neucleon cluster.

∙ 12y agoneutrons an electrons never meet, neutrons stay inside the neucleus and electrons stay outside, the main purpose of the neutrons is to create the strong force the electrons are there to take part in "bonding" and tradeing to create new atoms (when multiple atoms come together to make completely new atoms its called a neuclear reaction)
=) I LOVE PHYSICS!!!

Which phase of matter has the strong attractive force?
All phases of matter have the strong force. It is the force that occurs in the nuclei of atoms and holds the protons and neutrons together in the nucleus.
What form does chlorine occurs in nature?
it occurs as compounds, reacted with other elements, and can be separated through the process of electrolysis
What kind of change occurs when sulfur and sodium chloride are separated?

Force that affects all particles in a nucleus and acts only over a short range?
It is the strong nuclear force that holds the particles together in the nucleus. It is far stronger than the electromagnetic force over short ranges (particle separations of up to 2.5x10-15m), and so can overcome the repulsion that occurs between protons in the nucleus (typical distance approximately 1.25x10-15m) as a result of their positive charges.
The process of translation occurs in the?
Translation occurs in the ribosomes. Once mRNA has been synthesized, it is sent to the ribosomes, where it is translated to make proteins.
Which nuclear reaction occurs when two nuclei merge together to form one nucleus?
fusion
What kind of change occurs when a compond is separated into its components?
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
Transcription occurs in the what?
In eukaryotic cells transcription occurs in the cell nucleus.
Where in the cell transcription occurs?
It occurs in the nucleus of the cell.
Where does transcription occur in the cell?
It is in the nucleus.
Where transcription of mrna take place?
In eukaryotic cells, transcription occurs in the cell nucleus. In prokaryotic cells, which do not have a nucleus, transcription occurs in the cytoplasm.
How does a nucleus change when beta decay of the nucleus occurs?
The atomic number increases by one unit when a beta decay occurs.
Is nucleus is a organisim?
No. The nucleus is an organelle that occurs in the cells of eukaryotic organisms.
In the eukaryotic cell where does DNA replication occur?
it occurs in the nucleus...
Where in a eukaryotic cell does the process of transcription take place?
Transcription occurs in the cell nucleus and where DNA is housed. Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
Where in the cell does transcription and translation happen?
In prokaryotes (cells without nuclei), both transcription makes RNA from DNA and translation makes proteins from mRNA in the cytoplasm. In eukaryotes (cells with nuclei), transcription occurs in the nucleus, while translation occurs in the ribosomes of the cytoplasm.
In the nucleus of what element does the nucleon have the least mass?
It is in the atoms of iron that the nucleons have the least mass. Nucleons in iron have the highest binding energy per nucleon of any element. Want to know what the relationship is? Good. Let's review.The nucleons of an atom are the protons and neutrons that make up the nucleus of that atom. Neutrons have a mass of about 1.67 x 10-27 kg, and protons are slightly lighter than neutrons. But when protons and neutrons are fused together to form atomic nuclei (like in fusion reactions in stars), some of the mass of each nucleon is converted into binding energy or nuclear glue. It might be preferable to say that residual strong force is what holds atomic nuclei together. In any case, the "drop in mass" associated with the conversion of that mass to binding energy is called mass deficit. There are a number of complexities involved in nuclear formation, and when we look at different elements, there are different binding energies set up (during fusion) to keep the different nuclei together. Let's look in on that just a bit by taking a couple of examples.In helium (He-4), two protons and two neutrons are bound together in the nucleus. Each of the nucleons has "donated" some mass, which mediation by the strong interaction changed into nuclear glue. Each nucleon could be said to have donated mHe to allow the nucleus to stay together. In oxygen (O-16) however, each nucleon donated mO to the process creating binding energy for the oxygen nucleus. The nucleons in oxygen donated more of their mass, and these nucleons end up with less mass per nucleon than the nucleons in helium. See how that works? But there's a catch. There always is, isn't there?When we look at the amount of mass deficit a nucleon undergoes in different elements as we move up the periodic table, we see that an increasing amount of the mass of nucleons is converted into binding energy, as you might have guessed. But that all stops at iron. Iron nuclei are the most tightly bound nuclei of all the elements. As we move on up the periodic table from there, we see a decreasing amount of mass deficit in each nucleon of atomic nuclei. And that's the way it is. Completely explaining why this occurs would fill a semester of college physics. Use the link below to see the graph of binding energy per nucleon across the elements. (Note that iron sits at the peak.)
