What element has the highest binding energy per nucleon?
Iron
What happened in fission when the products have less mass than the starting material?
The binding energy per nucleon varies in different nuclei, being a maximum in the region of iron and nickel, and getting progressively less as the heavier nuclei are approached, Therefore when a uranium nucleus splits into two nuclei of lighter elements, the total binding energy is increased, and this results in a loss of mass. The destroyed mass appears as energy, from the relation E = mc2. You can read more and see the binding energy graph in the link below. It is also evident why fusion of light nuclei like hydrogen also releases energy, as in this part of the graph binding energy increases as the nuclei get heavier.
Is the binding energy the same for all nuclei?
No. Binding energy differs from element to element,
What is binding energy contributed to?
Nuclear energy is based on the release of binding energy.
How do you work out binding energy?
The binding energy is used in nuclear reactors.
Why does iron not yield energy if fused with something else?
Because iron has very little binding energy, to get it to fuse you must add binding energy. This takes a supernova explosion or a powerful particle accelerator. Elements lighter than iron have excess binding energy that can be releases by fusion, but not iron (or any heavier element).
Do atoms with the greatest mass have the greatest binding energies?
No. The maxiumum binding energy is of Iron nucleus (A=56) after which the binding energy starts decreasing.
What element has the highest binding energy per nucleon?
Iron
Why can't massive stars generate energy from iron fusion?
Because iron has no more excess binding energy left to release. Iron fusion consumes energy, it does not generate it.
Nuclide that have a high binding energy per nucleon are more?
Stable. The highest binding energy is for iron and nickel, which are the least likely to undergo fission or fusion reactions

How does mass relate to binding energy in the nucleus?
The mass defect represents the mass converted to binding energy
If in fission the splitting of a large atomic nucleus results in a release of energy why does fusion the combining of atomic nuclei to form a larger nucleus also release energy?
It is to do with the shape of the curve of nucleus binding energy vs mass number. This is a maximum for iron/nickel, and falls off for mass numbers both above and below this number. What this means is that when a large nucleus splits into fragments, orwhen light nuclei combine by fusion, the resulting nuclei have moved nearer to the binding energy maximum. There is therefore a mass deficit, which appears as released energy by E = mc2. Read more in the link below.
Why are lighter elements used in fusion reactions?
Because their binding energy is greater than that of their products, thus permitting an energy release. This is the same reason heavier elements are used in fission reactions. The range of elements from iron to lead has the lowest binding energy.
Is the binding energy the same for all nuclei?
No. Binding energy differs from element to element,
What is binding energy contributed to?
Nuclear energy is based on the release of binding energy.
Why iron binding increases in microcytic hypochromic anemia?
AS THERE IS IRON DEFICIENCY IN THIS TYPE OF ANEMIA,LOW SERUM IRON SO THERE WILL BE INCREASE IN BINDING OF IRON ITS A COMPENSATORY PROCESS .
