Calculate the average energy required to extract a nucleon from the nucleus of an `alpha ` - particle. the mass of 'alpha' -particle , proton and neutron are 4.00150 a.m.u 1.00728 a.m.u and 1.00867 amu respectively .

Explanation

To calculate the average energy required to extract a nucleon from the nucleus of an alpha particle, we will follow these steps:

### Step 1: Identify the components of the alpha particle
An alpha particle consists of:
- 2 protons
- 2 neutrons

### Step 2: Calculate the mass defect (Δm)
