Nuclear Fission and Chain Reaction

Nuclear Fission

Nuclear fission is one type of nuclear reaction . When a large nucleas breaks into small nucleas then it is called nucelar fisson reaction. In nuclear fission reactin a large amount of energy emits from the nucleas. For exmple- When 1 mole ureneam – 235  breaks up then about 200 mega electrone volt energy relase. It is really increatible amount of energy. It is very destructive if it cann’t be controlled.

Chain Reaction

When a large nucles is heated by a high velocity nutron then it breaks up  in a particuler way & this break continues in a cycle like a chain . This types of nucler reaction is known as chain reaction . If the chain reaction is not controlled then a huge blast can happen.
