Question

Which of the following orbitals has the maximum number of angular nodes?

• A. 3d
• B. 4d
• C. 5d
• D. all the above orbitals have the same number of angular nodes

Answer 1

The correct option is D all the above orbitals have the same number of angular nodes

Angular nodes depend only on azimuthal quantum number $\left(l\right)$ which is same for all the d orbitals i.e. $l=2$. Hence, all the above orbitals have the same number of angular nodes.
