Nucleons are protons and neutrons; the have a mass near 1.
But nucleons contain quarks and gluons.
I've been trying to work backward from the question to determine what you were really trying to ask, and I think it may have been something along the lines of "does uranium have the greatest mass deficit per nucleon"? In which case the answer is no. An isotope of nickel holds that position, with two iron isotopes close behind. Uranium is not even a contender; there actually aren't many elements that don't have at least one isotope that has a higher binding energy than any uranium isotope.
What else can I help you with?
A nucleon has the least mass in the nucleus of uranium iron plutonium hydrogen?
The masses of the nucleons are independent from the type of nucleus.
How does the mass per nucleon in uranium compare with the mass per nucleon in the fission fragments or uranium?
This is not something I really know anything about, but I do know that energy is liberated in the process, so you could expect it to be less in the fission fragments. It also depends on the nucleus. Proton and neutron masses differ somewhat, so it depends on what the ratio of protons and neutrons is as well.
How does the mass per nucleon in uranium compare with the mass per nucleon in the fission fragments of uranium?
The uranium nucleus has over 200 MeV more mass than the sum of the masses of the fission product nuclei plus the free neutrons emitted. Most of this energy appears as the kinetic energy of those particles and manifests as heat energy. Enough heat energy to cause the air around a bomb to radiate x-rays.
When does a nucleon have more mass?
A nucleon has more mass when it is not bound to the nucleus of an atom. When the nucleon is bound to other nucleons the binding energy that keeps them together comes from the mass of the nucleon. Therefore the mass of a single nucleon will be smaller in an atom than on it's own.
What happens to the mass per nucleon in uranium when it is split into smaller nuclei?
The mass per nucleon decreases when uranium is split into smaller nuclei through fission. This is because energy is released during the fission process, leading to a conversion of mass to energy based on Einstein's equation (E=mc^2).
How many neutrons are in the isotope uranium-238?
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
Where is most of the mass of an atom within the nucleus or outside of the nucleus?
The whole is less than the sum of the parts. A proton or neutron (nucleon) will have less mass in a nucleus that outside it. That's because some of the mass of a nucleon is converted into binding energy to hold an atomic nucleus together. That's the so-called mass deficit. Oh, and before we go, a proton or neutron is called a nucleon only inside the nucleus of an atom. We don't apply that term to either one when they're outside the nucleus.
How can you get the nucleon number?
The nucleon number, also known as the mass number, can be found by adding the number of protons and neutrons in an atomic nucleus. It is represented by the letter A in the notation of an element's isotopes.
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
How do you find the number of neutrons in the nucleus of uranium?
Number of neutrons in an atomic nucleus = Atomic mass of an isotope - Number of protons in the nucleus For uranium the number of protons is 92; each isotope has of course a different mass.
Compared to the mass of a uranium nucleus before splitting the pieces it splits into have?
The mass of the uranium nucleus after splitting into two pieces is slightly less than the mass of the original uranium nucleus before splitting. This is due to the conversion of a small amount of mass into energy in accordance with Einstein's famous equation, E=mc^2.
What is the Significance of binding energy per nucleon vary with mass number?
The binding energy per nucleon varies with mass number because it represents the average energy required to separate a nucleus into its individual nucleons. For lighter nuclei, the binding energy per nucleon increases as the nucleus becomes more stable. As nuclei become larger (higher mass number), the binding energy per nucleon decreases due to the diminishing strength of the nuclear force relative to the electrostatic repulsion between protons.
