The notation of orbital with `n=5` and `l=3` is

Options

A. 2p
B. 5s
C. 5f
D. 3d

Answer

To determine the notation of the orbital with \( n = 5 \) and \( l = 3 \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Principal Quantum Number (n)**:
- The principal quantum number \( n \) indicates the energy level or shell of the electron. Here, \( n = 5 \) means we are looking at the 5th energy level.

2. **Identify the Azimuthal Quantum Number (l)**:
- The azimuthal quantum number \( l \) determines the shape of the orbital. The values of \( l \) correspond to different types of orbitals:
- \( l = 0 \) corresponds to the s orbital
- \( l = 1 \) corresponds to the p orbital
- \( l = 2 \) corresponds to the d orbital
- \( l = 3 \) corresponds to the f orbital

3. **Combine the Quantum Numbers to Form the Orbital Notation**:
- Since \( l = 3 \), this indicates that we are dealing with an f orbital.
- Therefore, for \( n = 5 \) and \( l = 3 \), the notation for the orbital is \( 5f \).

### Final Answer:
The notation of the orbital with \( n = 5 \) and \( l = 3 \) is **5f**.
