The interaction produces a pair of particles, an electron and a positively charged positron. These two particles have the same mass, each equivalent to a rest mass […]

Why is energy released in a fission reaction?

Why is energy released in a fission reaction? Fission is the splitting of heavy nuclei (such as uranium) – in two smaller nuclei. This process needs less energy to ‘bind’ them together – so energy is released. The larger nuclei again needs less energy to hold it together – so energy is released. What is […]
