Which of the following nuclei is likely to have the largest mass defect per nucleon: ^{11}B, ^{51}V, ^{118}Sn, ^{243}Cm?

We’re being asked to** determine w****hich of the following nuclei **is likely to have the **largest mass defect **per nucleon:** ^{11}B, ^{51}V, ^{118}Sn, ^{243}Cm **based on the plot of

To do so, we need to do the following steps,

*Step 1**: Based on the plot, determine the nucleon with the highest binding energy.***Step 2**: Determine the nucleon with the largest mass defect (Δm) in kg, using the equation:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{\u2206}}{\mathbf{m}}{{\mathbf{c}}}^{{\mathbf{2}}}}$

**E = binding energy in J**

**Δ****m = mass defect in kg****c = speed of light = 3.0x10 ^{8} m/s**

**Step 1**: From the plot, we can see that the **binding energy of each nucleon increases**:
