Q. The nucleus $\ _{6}C^{12}$ absorbs an energetic neutron and emits a beta particle ($\beta)$ . The resulting nucleus is
A) $\ _{7}N^{14}$
B) $\ _{7}N^{13}$
C) $\ _{5}B^{13}$
D) $\ _{6}C^{13}$
Explanation
(b) $\ _{6}C^{12}\ + \ \ _{0}n^{1}\ \rightarrow \ _{7}N^{13}\ + \ \ _{- 1}e^{0}\ + \ \ \ \ \overline{v}$
(Neutron) (Beta (Anti
particle) neutrino)
On equating atomic numbers and atomic masses, the atomic number and atomic mass for resulting nucleus is 7 and 13, which is for nitrogen nucleus.
