The number of nodes palnes in a p_(y) orbital is

Options

A. One
B. Two
C. Three
D. Zero

Explanation

To determine the number of nodal planes in a p_y orbital, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Nodal Planes**:
- Nodal planes are imaginary planes where the probability of finding an electron is zero. For orbitals, these planes separate regions of positive and negative wave function values.

2. **Identify the Type of Orbital**:
- The p orbitals consist of three types: p_x, p_y, and p_z. Each of these orbitals has a distinct orientation in three-dimensional space.

3. **Determine the Nodal Planes for p Orbitals**:
- Each p orbital has one nodal plane. Specifically:
- The p_x orbital has a nodal plane at y-z plane.
- The p_y orbital has a nodal plane at x-z plane.
- The p_z orbital has a nodal plane at x-y plane.

4. **Conclusion**:
- Since the p_y orbital has one nodal plane, we can conclude that the number of nodal planes in the p_y orbital is **1**.

### Final Answer:
The number of nodal planes in a p_y orbital is **1**.
