Nuclear Fusion
Nuclear Fusion
Nuclear Fusion:
You have seen that when a heavy nucleus breaks into two middleweight nuclei, a lot of energy is liberated. Energy is also liberated when two light nuclei combine to form a single nucleus. This process is called nuclear fusion.
The process of two or more light nuclei combining to form a heavier nucleus is called nuclear fusion.
An example of nuclear fusion is given below where a deutron atoms fusses we get helium , a neutron and energy
Deuteron is the nucleus of deuterium, an isotope of hydrogen. Two deuterons combine to form the nucleus of helium-3, an isotope of helium. In this reaction, the mass of the product nucleus is less than the combined mass of the starting nuclei. The difference of mass is converted to energy, given by
.
The energy of the Sun comes from nuclear fusion in which, in a series of reactions, hydrogen gets converted into helium.
Which of the following are correct ? (a) The process of two or more light nuclei combining to form a heavier nucleus is called nuclear fission . (b) Deuteron is the nucleus of deuterium, an isotope of hydrogen. (c) Fusion has been used to make nuclear bombs that are more powerful than those based on fission these are called hydrogen bombs . | |||
