Write down the values of azimuthal quantum number possiblefor electron present in `3rd` shell.

Explanation

To find the values of the azimuthal quantum number (l) for electrons present in the 3rd shell (where the principal quantum number n = 3), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Principal Quantum Number (n)**:
- The principal quantum number (n) indicates the shell in which the electron is located. For the 3rd shell, we have n = 3.

2. **Determine the Possible Values of the Azimuthal Quantum Number (l)**:
