Question

Find the number of radial nodes in $3f$.

• A. 0.0
• B. 1
• C. 2
• D. Can't be predicted

Answer 1

The correct option is D Can't be predicted

For $3f$, $n=3$ and $l=3$.
But, the value of azimuthal quantum number $l$ should lie in the range of $0$ to $n-1$. So, $3f$ subshell does not exist. Hence, we cannot predict the number of radial nodes in $3f$.
