The number of radial nodes for an orbital is given by the formula:
Number of radial nodes = n − l − 1
where: - n is the principal quantum number. - l is the azimuthal quantum number
(orbital angular momentum quantum number).
For a 3p orbital: - n = 3 - l = 1 (since it is a p-orbital)
Applying the formula:
Number of radial nodes = 3 − 1 − 1 = 1
Conclusion: The number of radial nodes for the 3p orbital is 1.
