Vedclass · Answer

(B) The proton-proton cycle is a series of fusion reactions by which stars convert hydrogen to helium. $1$. The first step is the fusion of two protons to form a deuteron: $_1H^1 + _1H^1 	o _1H^2 + \beta^+ + 
u + Q$. $2$. The second step is the fusion of a deuteron with a proton to form helium-$3$: $_1H^2 + _1H^1 	o _2He^3 + Q$. $3$. The third step is the fusion of two helium-$3$ nuclei to form helium-$4$ and two protons: $_2He^3 + _2He^3 	o _2He^4 + 2(_1H^1) + Q$. Option $B$ $( _1H^2 + _1H^2 	o _2He^3 + _0n^1 + Q )$ involves the production of a neutron,which is not a characteristic step of the standard proton-proton cycle.
