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.
The surface temperature of a star is a key property used to determine what elements it can create through nuclear fusion in its core. Different elements require different temperatures to undergo fusion, with heavier elements typically requiring higher temperatures. This temperature determines the rate of nuclear reactions and the types of elements produced in a star.
No... Nuclear energy can be produced either by the fusion of 2 lighter nuclei or the fission of a heavier nucleus into 2 aprox equal nuclei by mass. Since Uranium has a very heavy nucleus, it can only undergo fission and not fusion. For generating energy through fusion, Hydrogen nuclei were the first to be used and are primarily preferred since hydrogen has a very light nucleus. Hydrogen fusion is what is the source of energy of the Sun and thus, the origin of the notion of nuclear fusion. The amount of energy produced by any nuclear reaction is given by Einsteins famous mass-energy relation - E=mc2 where c is the speed of light and m is the mass disappeared after the reaction.. NAMAN
Stars emit light through a process called "nuclear fusion", sometimes called "thermonuclear fusion". This should not be confused with "nuclear fission", the process used in nuclear power plants to produce electricity. In nuclear fission, the radioactive substance decays to a substance of lower atomic number (through bombardment of its nucleas), releasing considerable heat in the process. In nuclear fusion, the nuclei combine to form a substance of higher atomic number, again releasing considerable heat in the process.
Iron cannot release energy by fusion. When a star has used up all the lighter elements and has just iron left, it has no more nuclear "fuel". That causes the star to contract then explode very violently as a supernova.
They are made by stars through nuclear fusion. While we mostly use nuclear fusion just with hydrogen into helium, the nuclear fusion process can be used to make any and every element. All elements* up to Iron, yield energy during the fusion process. To procceed above iron, the fusion process takes energy, rather then supplying it. *minus a few select isotopes
This process is known as nuclear fusion. It occurs in stars like the sun when lighter elements such as hydrogen are combined to form heavier elements like helium, releasing a large amount of energy in the process.
Hydrogen and helium are the main elements used to create light in stars through the process of nuclear fusion in their cores. These elements undergo fusion reactions to produce energy, which is emitted as light and heat.
Common elements used in nuclear reactions include uranium, plutonium, and thorium. These elements have isotopes that are capable of undergoing nuclear fission or fusion, releasing energy in the process. Neutrons are typically used to initiate the reactions by bombarding the nucleus of the target element.
Substances known as fuel, typically isotopes of hydrogen such as deuterium and tritium, are used in fusion reactions. These isotopes are heated to high temperatures to create plasma, where fusion occurs. Additionally, certain elements like lithium can be used as part of the fusion reactor design to enhance the reaction process.

either uranium or plutonium may be used in fission bombs, hydrogen and/or lithium may be used in fusion bombs.
Uranium-235 is actually used in fission reactions, not fusion reactions. Uranium-235 is used in nuclear fission reactors because it is fissile, meaning it can undergo fission when bombarded by neutrons, releasing energy in the process. Fusion reactions, on the other hand, involve the merging of light atomic nuclei to form heavier ones, typically using isotopes of hydrogen like deuterium and tritium.
Carbon is not commonly used as nuclear fuel because it does not readily undergo nuclear fission reactions. Elements such as uranium and plutonium are more suitable for use as nuclear fuels due to their ability to sustain nuclear chain reactions.
Nuclear fusion and nuclear fission are two types of nuclear reactions that release energy. Fusion combines atomic nuclei to create heavier elements, while fission splits atomic nuclei into smaller fragments. Fusion powers the sun and hydrogen bombs, while fission is used in nuclear power plants and atomic bombs.
