In nuclear fusion, lighter atomic nuclei combine to form a heavier nucleus, releasing energy in the process. Since the total mass of the products is less than the sum of the masses of the initial nuclei (due to the released energy according to Einstein's mass-energy equivalence, E=mc^2), the mass per nucleon decreases after fusion.
What else can I help you with?
Is the total mass after fusion greater or less than before fusion?
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
In a nuclear fusion reaction the mass of the products is?
Less than 1%.
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.
What does the graph of mass per nucleon vs atomic mass number look like?
The graph of binding energy per nucleon versus mass number is an analog of this graph, except it would be upside down. Iron, which has the highest binding energy per nucleon, would have the least mass per nucleon as you looked across the periodic table. Use the link below to see the graph of binding energy per nucleon plotted against mass number. If you "invert" this graph, you'll have yours. If any uncertainty exists as to what is going on with "variable" mass among the nucleons of different elements, use the link below to the related question and investigate why things are the way they are.
What happens to the mass lost in nuclear fusion?
The mass lost in nuclear fusion is converted into energy according to Einstein's famous equation, E=mc^2. This energy is released in the form of photons, such as gamma rays, and contributes to sustaining the fusion reaction.
In nuclear fusion mass transforms into what?
In nuclear fusion mass transforms into energy.
Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
In nuclear fusion mass is tansformed into?
Energy
Does the mass of water change going from a liquid to a solid?
No. Mass never changes, except during nuclear fission and fusion.
What is the reaction of nuclear fusion?
Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass.
What does E equals mc2 have to do with nuclear fusion?
Some mass is "lost" during nuclear fusion and E = mc2 gives the amount of energy that this "lost" mass will be equal to.
The process of combining two small nuclei into one nucleus of larger mass is called?
Nuclear fusion. This process releases a large amount of energy due to the conversion of mass into energy as per Einstein's equation E=mc^2. Fusion reactions are the primary source of energy in the sun and other stars.
How nuclear fusion differ to nuclear fission in terms of energy release?
Energy from nuclear fusion is around 400 times more than that of nuclear fission for same mass.
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.
Is the total mass after fusion greater or less than before fusion?
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
In a nuclear fusion reaction how does the mass of the products compare to the mass of the reactants.?
In a nuclear fusion reaction, the mass of the products is slightly less than the mass of the reactants. This loss of mass is converted into energy according to Einstein's E=mc^2 equation. The difference in mass is known as the mass defect.
In a nuclear fusion reaction the mass of the products is?
Less than 1%.
