Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Decrease in atomic number is observed during: (1) alpha emission (2) positron emission (3) electron emission (4) beta emissionA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: A
Solution :
\[_{Z}{{X}^{A}}{{\xrightarrow{-\alpha }}_{Z-2}}{{Y}^{A-4}}\] (\[\alpha \] emission) \[_{Z}{{X}^{A}}{{\xrightarrow{-\beta }}_{Z+1}}{{Y}^{A}}\] (\[\beta \]emission) \[_{Z}{{X}^{A}}{{\xrightarrow[{}]{^{-}+1{{e}^{0}}}}_{Z-1}}{{Y}^{A}}\] (positron emission) \[_{Z}{{X}^{A}}{{+}_{-1}}{{e}^{0}}{{\xrightarrow[{}]{{}}}_{Z-1}}{{Y}^{A}}\] (electron capture)
