Chemistry - Mole Concept Question with Solution | TestHub

Any sub–orbit is represented as nl such that n is the principle quantum number (in the form of values) and l is the azimuthal quantum number (its name).

Value of m: –l to +l including 0,
Value of s:$+\frac{1}{2}$or$-\frac{1}{2}$
for 5f: n = 5, l = 3, m = any value between –3 to +3.
Hence n = 5, l = 3, m = +1, s =$+\frac{1}{2}$is the correct set. In other options these conditions are not satisfied so they are incorrect.
