Write notes on nuclear binding energy.
Nuclear binding energy refers to the energy required to separate the nucleons in a nucleus. It is the energy that holds the nucleus together. The mass of a nucleus is always less than the total mass of its individual nucleons, and the difference between the two masses is called the mass defect. This mass defect is converted into binding energy, which is released when a nucleus is formed from individual nucleons, and this energy can be harnessed for various applications, including nuclear power production.
