The characteristic of stars, such as our sun, is that their gravity keeps the nuclei present on them so close and hot that a fusion process is triggered, producing a huge amount of energy. On earth, ...

Explaining the process, Dr Aneeqa Khan, lecturer in nuclear materials at the University of Manchester, said: “Nuclear fusion is the process that powers the Sun, where two nuclei fuse together ...

In both cases, energy is freed because the mass of the remaining nucleus is smaller than the mass of the reacting nuclei. The reason why opposite processes release energy can be understood by ...

However as the number of protons increases, more neutrons are needed to keep the nucleus stable. For example lead, lead-206 has 82 protons and has 124 neutrons.

Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells. This compound was neither a ...

Nuclear chemistry is concerned with the properties of and changes to atomic nuclei, as opposed to traditional chemistry, which involves properties and changes related to the electronic structure ...

In fission, an unstable nucleus is converted into more stable nuclei with a smaller total mass. This difference in mass, the mass defect, is the binding energy that is released. In fusion ...
