X amount of energy is required to remove an electron from its orbit and Y amount of energy is required to remove a nucleon from the nucleus.

Options

A. `X=Y`
B. `XgtY`
C. `YgtX`
D. `XgeY`

Explanation

To solve the problem, we need to compare the energy required to remove an electron from its orbit (X) with the energy required to remove a nucleon from the nucleus (Y).

### Step-by-Step Solution:

1. **Identify the Energy Required to Remove an Electron (X)**:
- The energy required to remove an electron from its ground state in a hydrogen atom is approximately **13.6 eV** (electron volts).
- For other atoms, this energy is multiplied by \( Z^2 \), where \( Z \) is the atomic number of the element. However, for the sake of this comparison, we will consider the base case of hydrogen.

2. **Identify the Energy Required to Remove a Nucleon (Y)**:
- The energy required to remove a nucleon (which can be either a proton or a neutron) from the nucleus is significantly higher due to the strong nuclear force that binds nucleons together.
- The average energy required to remove a nucleon is about **6 to 10 MeV** (mega electron volts), where 1 MeV = \( 10^6 \) eV. This translates to approximately **6,000,000 eV to 10,000,000 eV**.

3. **Comparison of X and Y**:
- From the values we have:
- \( X \approx 13.6 \, \text{eV} \)
- \( Y \approx 6 \times 10^6 \, \text{eV} \) to \( 10 \times 10^6 \, \text{eV} \)
- Clearly, \( Y \) (energy to remove a nucleon) is much greater than \( X \) (energy to remove an electron).

4. **Conclusion**:
- Therefore, we conclude that \( Y > X \). The correct option is that the energy required to remove a nucleon from the nucleus (Y) is greater than the energy required to remove an electron from its orbit (X).

### Final Answer:
**Y is greater than X (Y > X)**.
