The probability of finding electron in XY plane for `P_(Z)` - orbital is

Options

A. `100%`
B. `50%`
C. `99.9%`
D. `0%`

Answer

To determine the probability of finding an electron in the XY plane for the Pz orbital, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Pz Orbital**:
- The Pz orbital is one of the three p orbitals (Px, Py, Pz) in an atom. The Pz orbital has a specific shape characterized by two lobes that extend along the Z-axis.

2. **Visualize the Orbital**:
- Imagine a three-dimensional coordinate system where the X, Y, and Z axes are defined. The lobes of the Pz orbital are oriented along the Z-axis, meaning they extend above and below the XY plane.

3. **Identify the XY Plane**:
- The XY plane is the flat surface where the Z-coordinate equals zero. In this plane, we are looking for the probability of finding an electron.

4. **Analyze the Electron Distribution**:
- Since the lobes of the Pz orbital are entirely along the Z-axis, there is no electron density in the XY plane. This means that if you were to slice through the atom at the XY plane, you would find no presence of the electron from the Pz orbital.

5. **Conclusion**:
- Therefore, the probability of finding an electron in the XY plane for the Pz orbital is 0%.

### Final Answer:
The probability of finding an electron in the XY plane for the Pz orbital is **0%**.
