The number of radial nodes for 3p orbital is......

Options

A. 3
B. 4
C. 2
D. 1

Explanation

To determine the number of radial nodes for the 3p orbital, we can follow these steps:

### Step 1: Understand the formula for radial nodes
The number of radial nodes in an orbital can be calculated using the formula:
\[ \text{Number of Radial Nodes} = n - l - 1 \]
where:
- \( n \) is the principal quantum number,
- \( l \) is the azimuthal quantum number.

### Step 2: Identify the values of \( n \) and \( l \)
For the 3p orbital:
- The principal quantum number \( n \) is 3.
- The azimuthal quantum number \( l \) for a p orbital is 1.

### Step 3: Substitute the values into the formula
Now, we can substitute the values of \( n \) and \( l \) into the formula:
\[ \text{Number of Radial Nodes} = 3 - 1 - 1 \]

### Step 4: Perform the calculation
Now, calculate the expression:
\[ 3 - 1 - 1 = 1 \]

### Step 5: Conclusion
The number of radial nodes for the 3p orbital is 1.

### Final Answer
The number of radial nodes for the 3p orbital is **1**.
