The binding energy per nucleon is maximum at A=56 and its value is around ____ Mev/ Nucleon

Options

A. 8.4
B. 8.7
C. 9
D. 7.8

Answer

To solve the question regarding the maximum binding energy per nucleon at A=56, we can follow these steps:

### Step 1: Identify the Element
The question states that the binding energy per nucleon is maximum at A=56. We know that A represents the mass number, which is the total number of protons and neutrons in the nucleus. The element with mass number 56 is Iron (Fe).

**Hint:** Remember that the mass number (A) is the sum of protons and neutrons in the nucleus.

### Step 2: Understand Binding Energy
Binding energy is the energy required to disassemble a nucleus into its individual nucleons (protons and neutrons). The binding energy per nucleon is the total binding energy divided by the number of nucleons. It is a measure of the stability of a nucleus.

**Hint:** Binding energy per nucleon gives an indication of how tightly the nucleons are held together in the nucleus.

### Step 3: Refer to the Graph
According to the information provided, we can refer to a graph that plots the binding energy per nucleon against the mass number (A). In this graph, we can observe that the binding energy per nucleon reaches its maximum value at A=56.

**Hint:** Graphs can be helpful in visualizing relationships between different physical quantities.

### Step 4: Determine the Value
From the graph, it is stated that the binding energy per nucleon for Iron (A=56) is approximately 8.75 MeV/nucleon. This value represents the maximum binding energy per nucleon.

**Hint:** Look for specific points on the graph that indicate maximum values.

### Step 5: Conclusion
Therefore, the binding energy per nucleon is maximum at A=56 (Iron) and its value is approximately 8.75 MeV/nucleon.

**Final Answer:** The value of the binding energy per nucleon at A=56 is around **8.75 MeV/nucleon**.
