Let’s first define the quantum numbers.

• the **principal quantum number (n) → **energy level in orbitals and its value could be **any positive integer** starting from 1

• **angular momentum quantum number (ℓ)**** ****→ ****(l) has to be at least 1 less than n, **range of values from** 0 up to (n-1)**

▪ Each **ℓ value **corresponds to a **subshell/sublevel**:

How would you determine the quantum number, m_{l}, for an element?
