To solve this problem, let’s first define the four quantum numbers:
- principal quantum number (n) →energy level in orbitals and its value could be any positive integer starting from 1 to infinity
- angular momentum quantum number (ℓ) → (l) has to be at least 1 less than n, range of values from 0 up to (n-1)
- magnetic quantum number (mℓ)→ range of values from -ℓ to +ℓ.
- spin quantum number (ms) → can only be +1/2 or -1/2
