The orbital with zero orbital angular momentum is.

Options

A. `s`
B. `p`
C. `d`
D. `f`

Explanation

To determine the orbital with zero orbital angular momentum, follow these steps:

### Step 1: Understand Orbital Angular Momentum
Orbital angular momentum is represented by the quantum number \( l \). The value of \( l \) determines the shape of the orbital and its angular momentum.

### Step 2: Identify the Quantum Number Values
Different types of orbitals correspond to specific values of \( l \):
- **s orbital**: \( l = 0 \)
- **p orbital**: \( l = 1 \)
- **d orbital**: \( l = 2 \)
- **f orbital**: \( l = 3 \)

### Step 3: Determine Which Orbital Has Zero Angular Momentum
Since we are looking for the orbital with zero angular momentum, we need to find the orbital where \( l = 0 \).

From the values identified:
- The **s orbital** has \( l = 0 \), which means it has zero orbital angular momentum.

### Step 4: Conclusion
The orbital with zero orbital angular momentum is the **s orbital**.

### Final Answer
**The orbital with zero orbital angular momentum is the s orbital.**
