Who invented nulcear fission?
It wasn't invented. It's a natural process that was discovered in heavier elements.
The source of fuel for fission reactors is?
"Binding energy." Absorption of neutrons by heavy elements, and fission of those heavy elements into lighter "fragments". The "lighter fragements" have a greater net binding energy than the heavier elements did.
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.
What are the differences of fission and fusion?
Fission is the process of taking a heavy element and splitting it into two or more smaller elements. Whereas fusion is the process of forming a heavier element by fusing two or more smaller elements.
What makes up a nuclear bomb?
Depends on the type of bomb. The first nuclear weapons were fission weapons- they used a heavy metal such as Uranium or Plutonium. These metals, when compressed by explosives, would undergo nuclear fission, and break into lighter elements, releasing heat and radiation. Later, larger bombs were fusion bombs. They used a fission bomb to start the nuclear reaction, but then used that energy to FUSE light elements, such as Deuterium and Tritium into heavier elements, releasing LARGE amounts of heat and radiation.
What it a process in which lighter elements stick together to create heavier elements?
The process in which lighter elements stick together to create heavier elements is known as fusion. This is the process that will be used in the synthesis of a heavier atomic nuclei.
What are the 3 main types of nuclear reactions?
Nuclear fission: When an element breaks apart to form lighter elements and other sub-atomic particles. Nuclear fusion: When two lighter elements fuse to form heavier ones.
What are fusion and fission with respect to nuclear physics?
Fission is a nuclear reaction where a heavy atom is split up into lighter elements, thereby producing energy. Fission is commonly used in nuclear power plants, but someday they will use fusion. Fusion is a nuclear reaction where very light elements are fused together under enormous heat and pressure into heavier elements, thereby producing energy. The Sun and all the stars are fusion reactors. Thermonuclear bombs (H-bombs) use fission (an A-bomb) to produce the heat needed for fusion.
How does nuclear fission happen in the central of the sun?
The Sun gets its energy from fusion, not from fission. Ocassionaly an atom of a heavier element might go through fission, but that's hardly relevant for the working of the Sun.The Sun gets its energy from fusion, not from fission.

What fuel is used by red giant stars?
After using up its hydrogen-1, the star becomes a red giant. It will start fusing helium-4 into heavier elements. It may also fuse heavier elements, to get other elements that are yet heavier.
What controls the fission reaction within a reactor core?
High neutron capture elements (e.g Boron, Cadmium ) are used to control fission reaction.
What is the process of the production of lighter nuclei from heavier nuclei called. Nuclear radiation nuclear force fusion or fission?
Nuclear fission
