nuclear+fission

Nuclear fission is a source of energy by splitting the nuclei of atoms. Uranium is the most common fuel used to produce energy by fission. The nuclei are split by having neutrons hurled at them, allowing three neutrons to be released and crash into other nuclei causing a chain reaction to produce continuous source of energy. In nuclear plants, this reaction is very closely controlled because it creates a huge amount of energy and if not harnessed could become dangerous. Example is nuclear bombs. Fission was discovered by Einstein and expanded upon by Marie Curie.



**[|Nuclear Fission]**: In nuclear fission, the nuclei of atoms are split, causing energy to be released. The [|atomic bomb] and nuclear reactors work by fission. The element uranium is the main fuel used to undergo nuclear fission to produce energy since it has many favorable properties. Uranium nuclei can be easily split by shooting neutrons at them. Also, once a uranium nucleus is split, multiple neutrons are released which are used to split other uranium nuclei. This phenomenon is known as a **chain reaction**.
