  The number of radial nodes for 3p orbitals is: (a) 3                                       (b) 4 (c) 2                                       (d) 1

Answer:

  (d) Number of radial nodes = \[n\text{ }-l\text{ }-1\] For 3p orbital, \[n=3,\,\,l=1\] \[\therefore \] Number of radial nodes \[=3-1-1=1\]
