How does nuclear fission differ from nuclear fusion?
Nuclear fission is the process of splitting a nucleus with a large mass into two nuclei with smaller masses. The energy released can then be used to produce electricity. Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass. The energy released by this reaction may someday be used to produce electricity. In other words, Nuclear Fusion is the exact opposite of Nuclear fission. While Nuclear Fission is splitting a nucleus into two nuclei, nuclear fusion is merging two nuclei into a nucleus.
Which best contrast nuclear fission and nuclear fusion?
Nuclear fission involves splitting a heavy nucleus into lighter elements, releasing energy. Nuclear fusion involves combining light nuclei to form heavier ones, also releasing energy. Fission is currently used in nuclear power plants, while fusion is still being developed as a potential future energy source.
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.
Is nuclear fusion more dangerous then nuclear fission?
We don't know much about fusion as it is still very experimental. It will not produce the dangerous fission products that fission does, but it may have other dangers unknown as yet. Nuclear fusion has more destructive potential than fission. Fusion is the principle powering the H-bomb developed in the Cold War. Just to put the power of a Fusion bomb in perspective, it is detonated by a fission bomb half the size of the one dropped on Japan. THAT'S JUST THE DETONATOR.
How is the production of electricity by fission better than nuclear fusion?
In principle fusion should be better for the environment because it does not produce the active fission products. The snag is that it has not been made to work yet, and won't be for many years to come, so as a practical way of producing electricity it does not come into play, and we have to say fission is better than a non-existent fusion

What method do we use for generating energy, nuclear fusion or fission?
Nuclear fission is the method currently used for generating energy, while nuclear fusion is still being developed for practical use.
What are the main types of nuclear energy?
The two types of nuclear energy are nuclear fission nuclear fusion. In nuclear fission, the nuclei of the atoms are split. In nuclear fusion, as the name suggests, the nuclei of the atoms are joined together.
Can you explain the difference between nuclear fusion and nuclear fission and how they differ in terms of energy production?
Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing a large amount of energy in the process. Nuclear fission, on the other hand, is the splitting of a heavy atomic nucleus into lighter nuclei, also releasing energy. In terms of energy production, nuclear fusion has the potential to produce more energy than nuclear fission, as it is the process that powers the sun and stars. However, nuclear fusion technology is still in the experimental stage and has not yet been successfully harnessed for large-scale energy production. Nuclear fission, on the other hand, is currently used in nuclear power plants to generate electricity, but it produces radioactive waste and carries the risk of meltdowns.
What are the two ways nuclear energy can be released?
Nuclear energy can be released through nuclear fission, which involves splitting atomic nuclei, or nuclear fusion, which involves combining atomic nuclei. Fission is used in current nuclear power plants, while fusion is still being researched for potential future energy applications.

What is nuclear energy made from?
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
Why is hydrogen bomb more powerful and destructive than the atom bomb?
The term atom bomb is somewhat ambiguous. The more precise distinction that you are trying to make is between a fission (or uranium or plutonium based) bomb and a fusion (or hydrogen based) bomb. The process of nuclear fission releases a certain amount of energy, and the process of nuclear fusion, per nucleus, releases a much larger amount of energy. Hence, you can build much bigger bombs based on fusion (although they still contain fission bombs which are required to create the high temperature needed for fusion).
Do fusion reactions provide nuclear power?

Why nuclear fission better?
Nuclear fission is now commercially available in nuclear fission reactors since the fifties of last century. Nuclear Fusion is still under R&D. Nuclear fission reactors are clean energy source.
