Vedclass · Answer

(B) In a nuclear reaction,both the total atomic number (sum of subscripts) and the total mass number (sum of superscripts) must be conserved on both sides of the equation.For option $A$: $3+1 = 4$ (atomic) and $7+1 = 8 
eq 7+1 = 8$. (Correct)For option $B$: $21+0 = 21$ and $20+0 = 20$. Since $21 
eq 20$,the atomic number is not conserved. (Incorrect)For option $C$: $33+2 = 35$ and $75+4 = 79 
eq 78+1 = 79$. (Correct)For option $D$: $83+1 = 84$ and $209+2 = 211 
eq 210+1 = 211$. (Correct)Therefore,option $B$ is not a balanced nuclear reaction.
