The maximum probability of finding an electron of a particular energy in an orbital is about

Options

A. `80%`
B. 0.85
C. 0.95
D. 0.99

Answer

To solve the question regarding the maximum probability of finding an electron in an orbital, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Orbitals**:
- An orbital is a region in space where there is a high probability of finding an electron. It does not have a definite size but is often represented as a sphere.

2. **Probability in Orbitals**:
- The probability of finding an electron at any point in an orbital is never zero. This means that there is always some chance of locating the electron within the orbital.

3. **Defining Maximum Probability**:
- The maximum probability of finding an electron in an orbital is typically expressed as a percentage. In quantum mechanics, it is commonly accepted that the region defined by an orbital encloses a significant percentage of the total probability of finding the electron.

4. **Common Probability Values**:
- For many orbitals, particularly the s-orbitals, it is stated that they enclose about 95% of the total probability of finding the electron. This means that the maximum probability of finding an electron in a specific energy state within an orbital is approximately 0.95 or 95%.

5. **Evaluating the Options**:
- Given the options: 0.80, 0.85, 0.95, and 0.99, the correct answer based on the understanding of orbitals and the probability distribution is 0.95.

### Final Answer:
The maximum probability of finding an electron of a particular energy in an orbital is about **0.95**.
