A) innermost electron orbit
B) a stable nucleus
C) outermost electron orbit
D) radioactive nucleus
Correct Answer: D
Solution :
\[\beta -\]emission takes place from a radioactive nucleus as \[_{15}^{32}P\xrightarrow{-\beta }_{16}^{31}S{{+}_{-1}}{{e}^{0}}+\overline{v}\] where\[\overline{v}\]is the anti-neutrino. In\[{{\beta }^{+}}\]decay a positron is emitted as \[_{11}^{22}Na\xrightarrow{{}}_{11}^{22}Ne{{+}_{+1}}{{e}^{0}}+v\] where\[v\]is the neutrino.
