Question

formula to find radial nodes​

Answer 1

Answer:

For the 3p orbital, the '3' means that 'n' = 3 and 'p' shows that 'ℓ' = 1. 'ℓ' also equals the number of angular nodes which means there is one angular node present. Using the equation for radial nodes, n - ℓ - 1 = 3 - 1 - 1 = 1. Thus there is one radial nodes.

Answer 2

There are two types of node: radial and angular.

The number of angular nodes is always equal to the orbital angular momentum quantum number, l.

The number of radial nodes = total number of nodes minus number of angular nodes = (n-1) - l.
