    In the nuclear reaction\[_{6}{{C}^{11}}{{\xrightarrow[{}]{{}}}_{5}}{{B}^{11}}+{{\beta }^{+}}+X,\]what dose X stand for?

    A) Electron              

    B) Proton

    C) Neutron             

    D) Neutrino

    Correct Answer: D

    Solution :

    The nucleus formed is\[_{z}{{X}^{A}}\]. Applying conservation of mass number \[11=11+0+A\Rightarrow A=0\] Now, from conservation of charge \[6=5+1+Z\]\[\Rightarrow \]Z = 0 Thus, X is express as\[_{0}{{X}^{0}}\]and hence neutrino
