Contrary to how many (including my younger self) envision the process, fission is not a process of a nucleon blasting its way into a nucleus, scattering the latter like a fast moving marble smashing into a group of other marbles. Instead, it results when a nucleus is too large to be stable for more than a few micro-seconds. This happens when a nucleus absorbs one too many nucleons. Thus, the best way to create fission is to send a nucleon into the nucleus that will absorb that nucleon.
It so happens that slow neutrons are BY FAR the most likely nucleons to absorbed by a nucleus, leading to a nucleus so unstable that it breaks apart. Protons and fast neutrons simply have so little chance of being absorbed, that they could never be used to create fission.
What else can I help you with?
Is it possible for an atom to have no neutrons?
A hydrogen atom is only a proton and an electron. Beyond that the neutron seems to keep the nucleus together and stable. Maybe a better question is, "What is the difference between a hydrogen atom without an electron and a proton?"
What to use to cover paneling paint or wallpaper?
Vinyl wall panels, especially in bathrooms, are better off if they are removed as opposed to covered. They can warp, swell, and peel, causing damage to new coverings, and if they are found in a room with a high moisture content, they can trap moisture behind them, causing mold.
What cause a Rough idle in 70 DEGREES OR BELOW weather in a 2001 Ford Escape?
We have a 2001 ford escape. It would idle horrible in the morning when it was cold, but would run much better when it warmed up. After a year of problems, cylinders misfiring ect, and part after part change, we finally changed the upper and lower intake gaskets and the problem seems to be fixed. Starts up good as new. The worn gaskets didn't seal properly causing the misfiring cylinders, but when the faulty gaskets warm up they expand causing it to seal better and that's why it would run better when warm. Anyway, it could be a bunch of different things, but this seems to be the problem for us. Several other forum members discussing same issue have also said it was the intake gaskets also. If you can fix it yourself you will save a load of money.
Is there something you can put over finished wood so you can paint it without it peeling?
A wood Primer is required to coat the wood before the paint is applied. The Primer seals the wood and is better suited to being painted as the wood alone will soak up the paint causing it to dry too quickly and peel.
Is Denny's better than Perkins?
Depends on what you get, Perkins has better breakfasts in my opinion, while Dennys has better lunches, and dinners.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
When the atoms center is found what will be found?
When the center of an atom is found, it will contain the nucleus which is made up of protons and neutrons. The electrons, which have much smaller mass than protons and neutrons, will be found orbiting around the nucleus in specific energy levels or shells.
What is the combined name for protons and neutrons?
There is no simple combined term for both of them, but you can refer to them as the nucleus of the atom. Particles made of three quarks are called baryons. This includes the proton and neutron but would also include and anti-proton. (A neutron is its own antiparticle)
Why don't protons get pulled into neutrons in an atom?
I might be able to answer better if I knew why you think this should (or even COULD) happen. In the Standard Model, both protons and neutrons are composed of three quarks (up, up, down for protons and up, down, down for neutrons). These arrangements are much more stable than any hypothetical six quark structure that would be produced by combining them.
What holds protrons and neutrons together in the nucleus?
The so-called "strong force". It is, precisely, a force between nucleons (protons and neutrons), acts only at very short distances, and is a different force from the better-known electric, magnetic and gravitational forces.The so-called "strong force".

How many particles are in the nucleus give their name and description?
uh, you could probably get a better description than what i tell you if you typed that question in google. but basically, theres two particles found in the nucleus, they are called The Protons and The Neutrons. Protons have a positive charge, and Neutrons have no charge. hope that helped a tad :)
What is fission temperature?
Fission temperature refers to the temperature at which nuclear fission reactions can occur. For uranium-235, which is commonly used in nuclear reactors, the optimal fission temperature is around 572°F (300°C). Controlling the fission temperature is crucial for maintaining the stability and efficiency of a nuclear power plant.
Why are neutrons needed to hold the nucleus together?
Atoms never have two or more protons in their nucleus without having at least one neutron (or more). Protons don't like each other. They have a positive electrostatic charge, and like charges repel each other. So protons alone cannot make up an atomic nucleus. Enter, the neutron. When atoms are created by fusion, neutrons are included in the construction. They have to be. In fusion, the building blocks of a new atomic nucleus are "smooshed" together, and all of the particles undergo a mass change. Each nucleon loses a bit of mass, and that mass is converted into nuclear binding energy or nuclear glue. And it is this stuff that makes the protons stick together (with the neutrons). It takes protons and neutrons to contribute to the creation of binding energy to cause a nucleus to fuse together.The hydrogen-1 isotope (the most abundant form of hydrogen) has no neutrons, which is possible because it only has one proton.
Are protons electrons neutrons and quarks equal in mass?
Protons and neutrons are in atomic nuclei, while electrons are located outside atomic nuclei in various probabilities of energetically favored states. Quarks are the fundamental particles that compose the hadron family of particles, of which protons and neutrons are members. Thus, you better believe quarks are found in atomic nuclei! In fact, because of the way the strong nuclear force acts on quarks, they can never be found on their own they are not found on their own at low energies but it is possible that they can become free at extremely high energies, as is the case in the hypothetical quark-gluon plasma. As we can observe them, however, they're always in protons and neutrons (or the various other hadrons).
Why is it eaier to fission uranium 235 with neutrons than alpha particles?
A neutron is smaller and has no charge, so it is able to penetrate to the nucleus far better than an alpha particle (which is larger in size, and has a charge that is repelled by the nucleus). So the neutron is more able to cause critical instability and fission the nucleus.
Why neutrons more effective than protons as nuclear bullets?
One reason for using a neutron as a nuclear bullet is that it isn't deflected by magnetic or electrostatic fields like a proton or other ion would be. About the only thing that will slow down or deflect (scatter), or stop (absorb) a neutron is an atomic nucleus. Neutrons have many times more penetrating power than protons.
Is the nucleus a part of both an atom and a cell or just one?
Both. The nucleus of a cell is its "brain" for lack of a better term. The nucleus of an atom is where the protons and neutrons are found, and is the region that the electrons orbit.
