Question

Angular distribution functions of all orbitals have:

• A. $l$ nodal surfaces
• B. $(l-1)$ nodal surfaces
• C. $(n+l)$ nodal surfaces
• D. $(n-l-1)$ nodal surfaces

Answer 1

The correct option is A $l$ nodal surfaces

Angular node is also called nodal plane. Angular node is a plane that passing through the nucleus.The quantum number l determines the number of angular nodes. Angular node is equal to the azimuthal quantum number (l).
