For 3p-orbital, number of radial nodes = n - l - 1 = 3 - 1 - 1 = 3 - 2 = 1 Number of angular nodes = l = 1 Number of radial and angular nodes depend on both n and l.

Q. Assertion: Number of radial and angular nodes for $3 p$ -orbital are 1, 1 respectively.
Reason: Number of radial and angular nodes depends only on principal quantum number.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

For $3 p$ -orbital, number of radial nodes

$= n - l - 1 = 3 - 1 - 1 = 3 - 2 = 1$

Number of angular nodes $= l = 1$

Number of radial and angular nodes depend on both n and $l$ .
