A subshell with `l=2` is called

Options

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

Explanation

To determine what a subshell with \( l = 2 \) is called, we can follow these steps:

### Step 1: Understand the Quantum Numbers
The angular momentum quantum number, denoted as \( l \), determines the shape of the orbital and the type of subshell. The values of \( l \) correspond to different subshells as follows:
- \( l = 0 \) corresponds to the **s** subshell
- \( l = 1 \) corresponds to the **p** subshell
- \( l = 2 \) corresponds to the **d** subshell
- \( l = 3 \) corresponds to the **f** subshell

### Step 2: Identify the Subshell for \( l = 2 \)
Since we are given \( l = 2 \), we can refer to the list above. According to the quantum number definitions:
- For \( l = 2 \), the subshell is called the **d** subshell.

### Step 3: Conclusion
Thus, a subshell with \( l = 2 \) is called the **d subshell**.

### Final Answer
A subshell with \( l = 2 \) is called the **d subshell**.
