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

• A. $\left(M_{O}-8M_{P}\right)C^{2}$
• B. $\left(M_{O}-8M_{P}-9M_N\right)C^{2}$
• C. $M_OC^2$
• D. $\left(M_{O}-17M_{N}\right)C^{2}$

Answer 1

Answer: (B)

$\left(M_{O}-8M_{P}-9M_N\right)C^{2}$

Answer 2

Binding energy $=\left(M_{O}-8M_{P}-9\,M_N\right)C^{2}$
