Web8 apr. 2024 · Similarly for isotope $^{15}N$ is $14$ let us assume number of neutrons are n’ the mass number is sum of number of protons which are $7$ and number of neutron n’ so, we have \[15 = 7 + n'\] $\therefore n' = 8$ Hence, the number of protons in isotopes $^{14}N$ and ${^{15}}N$ are $7.$ and number of neutrons are $7$ and $8$ respectively. Web8 protons and 10 neutrons Nitrogen (N) is made up of 99.632% 14N and 0.368% 15N. The atomic mass of 14N is 14.003 amu. The atomic mass of 15N is 15.000 amu.
