Options

A. ionisation energy
B. binding energy
C. excitation energy
D. kinetic energy

Answer

To solve the question, "The minimum energy needed to separate the constituents of a nucleon system is known as," we will follow these steps:

### Step 1: Understand the Components of a Nucleon System
A nucleon system consists of protons and neutrons, which are the building blocks of atomic nuclei. Protons are positively charged, while neutrons are neutral.

**Hint:** Recall that nucleons are found in the nucleus of an atom, and they are held together by nuclear forces.

### Step 2: Identify the Forces at Play
In a nucleon system, protons experience electrostatic repulsion due to their positive charges. To keep the nucleons together, a stronger force is needed, which is provided by nuclear forces.

**Hint:** Consider how the forces between charged particles work, especially the repulsion between like charges.

### Step 3: Define the Energy Required to Overcome Forces
To separate the nucleons, we need to overcome the attractive nuclear forces that hold them together. The minimum energy required to achieve this separation is a crucial concept in nuclear physics.

**Hint:** Think about what happens when you try to pull apart particles that are held together by a strong force.

### Step 4: Introduce the Concept of Binding Energy
The minimum energy required to separate the constituents of a nucleon system is referred to as "binding energy." This energy represents the work done to separate the nucleons from each other.

**Hint:** Binding energy is a key term in nuclear physics; it quantifies the stability of a nucleus.

### Step 5: Understand the Binding Energy Formula
The binding energy can be calculated using the formula:
\[ \text{Binding Energy} (E) = \Delta m \cdot c^2 \]
where \(\Delta m\) is the mass defect (the difference between the mass of the separated nucleons and the original mass of the nucleus) and \(c\) is the speed of light.

**Hint:** Remember that mass defect arises because the mass of the nucleus is less than the sum of the masses of its individual nucleons.

### Conclusion
The minimum energy needed to separate the constituents of a nucleon system is known as **binding energy**.
