363818 Statement A :
The detection of neutrions is extremely difficult.
Statement B :
Neutrions only interact very weakly with matter.

363819 Assertion :
\({}_7^{14}N\) is stable.
Reason :
Nuclei having an odd number of protons and an odd number of neutrons are generally less stable than the one having even number of protons and even number of neutrons.

363820 Observe the following statements regarding isotones
I. \(^{39}{K_{19}}\) and \(^{40}C{a_{20}}\) are isotones
II. Nuclides having different atomic numbers \((z)\) and mass number \((A)\) but same number of neutrons \((n)\) are called Isotones
III. \(^{19}{F_9}\) and \(^{23}N{a_{11}}\) are isotones
The correct answer is

363821 The stable isotopes \({ }_{3}^{6} \mathrm{Li}\) and \({ }_{3}^{7} \mathrm{Li}\) have respective abundance of \(7.5 \%\) and \(92.5 \%\). These isotopes have masses \(6.01512\,u\) and \(7.01600\,u\) respectively. The atomic weight of lithium is:
