Question:

If $M_O$ is the mass of an oxygen isotope $_{8}O^{17}, M_{P}$ and $M_{N}$ are the masses of a proton and a neutron respectively, the nuclear binding energy of the isotope is

Updated On: Jul 31, 2023
  • $\left(M_{O}-8M_{P}\right)C^{2}$
  • $\left(M_{O}-8M_{P}-9M_N\right)C^{2}$
  • $M_OC^2$
  • $\left(M_{O}-17M_{N}\right)C^{2}$

Nuclei

In the year 1911, Rutherford discovered the atomic nucleus along with his associates. It is already known that every atom is manufactured of positive charge and mass in the form of a nucleus that is concentrated at the center of the atom. More than 99.9% of the mass of an atom is located in the nucleus. Additionally, the size of the atom is of the order of 10-10 m and that of the nucleus is of the order of 10-15 m.
