Nuclear+Fission+and+Fusion

What is the difference and give examples of fission and fusion?

What is the difference between nuclear fission and nuclear fusion? Nuclear fission is the process used in the production of nuclear power. Fission involves splitting the nucleus of a heavy atom, such as uranium. This yields two or more lighter nuclei and a large amount of energy. Fusion, on the other hand, is the combination of two hydrogen nuclei into one helium nucleus, under conditions of extreme heat and pressure. Fusion is the process by which energy is created in the sun. While the hydrogen bomb relies on fusion, fusion has not yet been used in the production of nuclear power. The latter fact is primarily because it is extremely expensive to create the conditions necessary to begin a fusion reaction. A process called "cold fusion," which does not require heat, is currently in the experimental stages. Pasted from <[]>

When Uranium-238 decays, it turns into thorium-234 and an alpha particle. When we add the mass numbers and atomic numbers of both products, it should equal to the mass number and the atomic number of the radioactive nuclei. There for if we had Thorium-234's mass number (which is 234) and add the alpha particle's mass number (which is 4) it should add up to the Uranium-238's mass number (which is 238). Same goes for the atomic number.
