Question

Write the principle behind the Hydrogen bomb.

Answer 1

The hydrogen bomb is based on fusion reaction of hydrogen to form helium producing large amount of energy. Hydrogen bomb consists of an arrangement for nuclear fission in the centre surrounded by a mixture of deuterium and lithium isotope. Fission reaction provides the high temperature necessary to start the fusion.
i) Fission $\to$ heat $+$neutrons.
ii) ${}_{3}L{i}^6{+}_o{n}^1{\to }_1{H}^3{+}_{2}H{e}^4+4.78$MeV
iii) ${}_1{H}^2{+}_1{H}^3{\to }_{2}H{e}^4{+}_o{n}^1+17.6$MeV.
