Not sure what you mean by points, but the

- a principal quantum number
#n = 3# , placing it on the third energy level. - an angular momentum quantum number
#l = 1# , giving it the shape of a#p# orbital.

The number of **radial nodes**, otherwise known as spherical shell nodes, is given by

#n - l - 1 = 3 - 1 - 1 = bb1# radial nodein the

#3p# orbital (see the green circle in the image above).

The number of **angular nodes** (or nodal planes, for orbitals that are not the

#l = bb1# angular node (here, nodal plane)in the

#3p# orbital (the plane perpendicular to the orbital axis).

Thus, the total number of nodes (regardless of type) is given by

#n - 1 = 3 - 1 = bb2# total nodes in generalin the#3p# orbital.

Nodal planes are depicted more explicitly here:
