Menstion the values of n and l corresponding to the following orbitals.
(a) 2s (b) 2p (c ) 3d (d) 4f ( e) 3s

Explanation

To determine the values of the principal quantum number (n) and the azimuthal quantum number (l) for the given orbitals, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Orbital**: Start with the first orbital, which is **2s**.
- **Principal Quantum Number (n)**: The first number indicates the shell, so for **2s**, n = 2.
- **Azimuthal Quantum Number (l)**: For the 's' subshell, l = 0.
- **Result**: For 2s, (n, l) = (2, 0).
