A) \[{{\,}_{12}}M{{g}^{23}}\]
B) \[{{\,}_{2}}H{{e}^{3}}\]
C) \[{{\,}_{82}}P{{b}^{207}}\]
D) None of these
Correct Answer: C
Solution :
(c)\[{{\,}_{82}}P{{b}^{207}},\]\[\frac{n}{p}=\frac{125}{82}=1.53>1,\]stable (a) \[{{\,}_{12}}M{{g}^{23}},\,\frac{n}{p}<1,\]unstable (b)\[{{\,}_{2}}H{{e}^{3}},\frac{n}{p}=\frac{1}{2}=0.5<1,\] unstable
