Question

calculate the total no. of angular nodes and radial nodes present in 3p and 4d orbitals.

Answer 1

For 3p:

n = 3 and â„“ = 1 because of the p orbital.

nodes = n-1. In this case, 3-1=2, so there is a total of 2 nodes.

The quantum number â„“ tells us how many angular nodes there are, so there is 1 angular node. Since there is one node left, there must be one radial node.

Therefore, 3p orbital has 2 nodes: 1 angular node and 1 radial node.
