A) neutrino
B) antineutrino
C) proton
D) neutron
Correct Answer: C
Solution :
Key Idea: Mass number and atomic number in nuclear reactions are conserved. The nuclear reaction is as follows. \[{{\,}_{7}}{{N}^{14}}+{{\,}_{2}}H{{e}^{4}}\xrightarrow{{}}{{\,}_{8}}{{O}^{17}}+{{\,}_{q}}{{X}^{p}}\] Conservation of mass number gives \[p=14+4-17=1\] Conservation of atomic number gives \[q=7+2-8=1\] Hence, particle is a proton \[{{\,}_{1}}{{H}^{1}}.\]You need to login to perform this action.
