The nucleus of an atom with an atomic mass of $24$ and atomic number $11$ consists of:

Express unified atomic mass unit $(amu)$ in $kg$.

For effective nuclear forces,the distance should be

For a nucleus to be stable,the correct relation between neutron number $N$ and proton number $Z$ is

Nuclear reactions are given as $(i)$ $(n, p) {}_{16}S^{32} \to {}_{15}P^{32}$,$(ii)$ $(p, \alpha) {}_{8}O^{16} \to {}_{9}F^{19}$,$(iii)$ ${}_{7}N^{14} + ? \to {}_{6}C^{14} + {}_{1}H^{1}$. The missing particles or nuclides in these reactions are respectively:

The atomic masses of two isotopes of an element are $34.98 \ u$ and $36.98 \ u$ and their relative abundances are $75.4 \%$ and $24.6 \%$ respectively. The average atomic mass of the element is: (in $u$)
