NUCLEAR FUSION-RADIOACTIVITY

NUCLEAR FUSION: -

“The process of forming heavy nucleus from two or more light nuclei in which energy is released is called ‘NUCLEAR FUSSION’ ”   

OR

“The combining of two lighter nuclei to form a relatively heavier nucleus with the release of energy is called ‘NUCLEAR FUSSION’ ”

EXAMPLE: -

FUSSION OF DEUTERIUM AND TRITIUM: -

When ₁H² and ₁H³ nuclei are brought together they form ₂He⁴ nucleus with the re3lease of energy.

CHARACTERISTICS OF FUSION: -
(1)  (1)   Energy release during a fusion process in greater than that of fission. (2)   To produce a fusion process a very high temperature is required to overcome repulsion between positive nuclei.
