What is the binding energy of the hydrogen nucleus?

Options

A. zero
B. 13.6 eV
C. More than 13.6 eV
D. Infinite

Explanation

To find the binding energy of the hydrogen nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Binding Energy**: Binding energy is defined as the energy required to separate all the particles in a nucleus completely. It is the energy needed to overcome the forces that hold the nucleus together.

2. **Identify the Composition of the Hydrogen Nucleus**: The hydrogen nucleus, also known as a proton, consists of only one proton and no neutrons.

3. **Consider the Implications of Having Only One Proton**: Since the hydrogen nucleus has only one proton, there are no other nucleons (neutrons or protons) to bind it to. Therefore, there are no forces acting to hold it together with other particles.

4. **Calculate the Binding Energy**: Given that there are no additional particles to bind, the energy required to separate the proton from itself is effectively zero. Thus, the binding energy of the hydrogen nucleus is zero.

5. **Conclusion**: Therefore, the binding energy of the hydrogen nucleus is 0 MeV.

### Final Answer:
The binding energy of the hydrogen nucleus is **0 MeV**.
