  • question_answer
    A nucleus decays by \[{{\beta }^{+}}\] emission followed by a gamma emission. If the atomic and mass numbers of the parent nucleus are Z and A respectively, the corresponding numbers for the daughter nucleus are respectively.

    A) \[Z-1\] and \[A-1\]

    B) \[Z+1\] and \[A\]

    C) \[Z-1\] and \[A\]

    D) \[Z+1\] and

    Correct Answer: C

    Solution :

    [c] After \[{{\beta }^{+}}{{(}_{+1}}{{e}^{0}})\] emission atomic number decreases by one and mass number remain unchanged. g-emission, there will be no change on mass number and atomic number.
