Gcse physics revision science section covering nuclear energy uranium fission nuclear fuel nuclear power stations atoms chain reactions nuclear fusion and half life and decay. It involves taking smaller nuclei and bringing them together to form a bigger nucleus. Fusion is the opposite of that.
Fission is the process in which large nuclei are split into two smaller nuclei releasing energy in the process. Explain the difference between nuclear fusion and nuclear fission. 4 4 2 nuclear fusion samabrhms11 2020 02 12t15 42 08 00 00 fusion when small nuclei are fused together the mass of the final nucleus is slightly less than the combined mass of the original nuclei.
Basically fission means splitting nuclear fission is where a nucleus is split the nuclei of uranium and plutonium are both pretty large which makes them easier to split. The reaction that takes place in nuclear power stations is known as nuclear fission the most commonly used isotope is uranium 235 although some use plutonium 239. In order to undergo nuclear fission a nucleus usually requires some energy which can be given by hitting the nucleus with a neutron.
Usually large unstable nuclei break up gradually by the process of radioactive decay but a small number including uranium 235 a naturally occuring isotope of uranium can break up in one big go a process known as nuclear fission. Against nuclear fusion the technological difficulties of fusion reactors are difficult to overcome. Nuclear fusion releases four times more energy per kg than a nuclear fission reaction.
In one of the fusion. Nuclear fusion reactions happen naturally in stars such as our sun. Nuclear fusion is a process in which two relatively small nuclei join together to make one larger nucleus.
The nuclei fuse together and energy is released. Nuclear fusion occurs when two small light nuclei join together to make one heavier nucleus. Fusion reactions occur in stars where two hydrogen nuclei fuse together under high temperatures and pressure.
Nuclear fusion is when two small light nuclei join together to make one heavy nucleus.
Nuclear fusion diagram gcse. Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. In a nuclear reactor a neutron is absorbed into a nucleus typically uranium 235. This causes the nucleus to.
