Probability of finding an electrons at the nodal surface is

Options

A. unity
B. low
C. high
D. zero

Answer

To solve the question regarding the probability of finding an electron at the nodal surface, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Nodal Surface**:
- A nodal surface is defined as a region in space where the probability of finding an electron is zero. This means that within this surface, there are no chances of locating an electron.

2. **Define Probability in Quantum Mechanics**:
- In quantum mechanics, the probability of finding an electron in a given region is determined by the square of the wave function (ψ) associated with that electron. If the wave function is zero, then the probability is also zero.

3. **Apply the Definition to Nodal Surfaces**:
- Since a nodal surface is characterized by a wave function that equals zero, we can conclude that the probability of finding an electron at this surface is also zero.

4. **Conclude the Answer**:
- Therefore, the probability of finding an electron at the nodal surface is 0.

### Final Answer:
The probability of finding an electron at the nodal surface is **0**.
