Chapter 11: Q22E (page 518)

Calculate the binding energy per nucleon of technetium - $98$ .

Short Answer

Expert verified

Binding energy per nucleons is $8.61 \frac{MeV}{nucleon}$ .

Step by step solution

Given data

Total number of nucleons, $A = 98$ .

Technetium-98 has $Z ($ proton $) = 43$ and $N ($ neutron $) = A - Z = 98 - 43 = 55$ .

Atomic number of hydrogen, $m_{H} = 1.007825 u$ .

Mass of neutron, $m_{n} = 1.008665 u$ .

Speed of light, $c = 3 \times 10^{8} m / s$ .

Atomic mass of technetium, $M_{\frac{q 8}{43}} Tc = 97.907115 u$ .

Formula for Binding energy

For helium- $4$ , binding energy is given by formula, $B E = (Z m_{H} + N m_{n} - M_{\frac{4}{1} x}) c^{2}$ .

Calculation for the binding energy per nucleons

The binding energy per nucleons is given as:

$\begin{array}{l} \frac{B . E}{nucleon} = ({Zm}_{H} + N m_{n} - M_{\frac{?}{43} Tc}) c^{2} \\ \frac{B . E}{nucleon} = \frac{[43 (1.007825 u) + 55 (1.008665 u) - 97.907115 u] c^{2}}{98} \end{array}$

The conversion factor may be used to express $c^{2}$ in $MeV / u$ .

$\begin{array}{l} \frac{B.E.}{nucleon} = \frac{[43 (1.007825 u) + 55 (1.008665 u) - 97.907115 u] (931.5 \frac{MeV}{u})}{98 nucleons} \\ \frac{B.E.}{nucleon} = 8.61 \frac{MeV}{nucleon} \end{array}$

Therefore, binding energy per nucleons is $8.61 \frac{MeV}{nucleon}$ .
