Compare nuclear fission and nuclear fusion?
Nuclear fusion is the process of squeezing two lighter atoms together to make heavier atoms; nuclear fission is the process of splitting heavier atoms into lighter ones. In both processes, some of the mass of the original atoms are converted into energy; fusion tends to convert more mass into energy than fission does, so fusion tends to create more energy. Heavier atoms needed for a fission chain reaction tend to be unstable and radioactive, and thus the fission process tends to produce more radioactivity.
Do fusion reactions provide nuclear power?
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
What is needed to produce different isotopes during fission?
The fission reaction must be possible.

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.

What particle is needed to begin a nuclear chain reaction?
Neutrons are the important particles of nuclear chain reactions and the reactions depend on them. The neutrons do not really start the fission, reaction, however, because the neutrons come from fission in the fuel.The material in the fuel, typically a mix of 235U and 238U, undergoes fission spontaneously. When a fission event happens, more neutrons, typically two or three, are emitted. These bounce about from atom to atom, until they cause another atom to undergo fission, releasing more neutrons to increase the rate at which atoms undergo fission.But the neutrons needed for the chain reaction are actually produced by the fuel spontaneously, and these are produce in an ongoing manner with or without critical mass. So it is not a particle that starts the chain reaction; it is the act of putting together a critical mass.
What particle is needed to begin nuclear chain reaction?
Neutron particle is needed to begin nuclear chain reaction.
What is the source of energy in nuclear power plants?
The source of energy in almost all nuclear power plants is fission or the splitting of the atom. There are a few experimental fusion power plants, (or the joining of the atoms), but, there are few of them, since the energy needed to produce fusion is extremly high, and only last a few seconds. Around 99.99% of nuclear power plants are fission power plants.

What is nuclear energy and what are its uses?
It is energy that comes from nuclear fission where an energetic neutron splits an molecule into to creating more energetic neutrons and molecule and releases the energy needed for the atoms in the molecule to stick together. It can be used as bombs or to power ships, submarines and cities.

What forms of energy are needed to create Nuclear energy?
Nuclear energy results from fission of uranium or plutonium. No outside energy is needed. An assembly of uranium or plutonium with a moderator which slows down the fast neutrons produced in fission, will start to produce power when it is made critical. There are always occurring some spontaneous fissions in the fuel material, and all that is needed is to build a critical assembly, that is one where a chain reaction is set up, and the power level will build up until it reaches the desired level, whereupon it is stabilised by introducing some neutron absorption, and it will continue at power until the fuel starts to get depleted in fissile material, after which new fuel has to be loaded.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
