We are asked to **calculate the nuclear binding energy** in mega electronvolts (MeV) per nucleon for ^{172}**Ta which has an atomic mass of 171.944740**

To calculate for the nuclear binding energy:

**Step 1:** Determine the number of protons and neutrons

**Step 2:** Determine the total mass of protons and neutrons

**Step 3:** Calculate the mass defect (∆m)

**Step 4:** Determine nuclear binding energy per nucleon

An atom of ^{172}Ta has a mass of 171.944740 amu. Calculate the binding energy in MeV per atom. Use the masses:

mass of ^{1}H atom = 1.007825 amu

mass of a neutron = 1.008665 amu

1 amu = 931.5 MeV

Give your answer to 4 significant figures and DO NOT use E notation. No charity points will be awarded.......

a. 7.769 MeV

b. 12.421 MeV

c. 2.366 MeV

d. 1.523 MeV

e. 1.434 MeV
