The orbit angular momentum and  orbital angular momentum for electron are 3h2π and 32hπ Then the number of radial nodes and angular nodes for that atomic orbital will be

Orbit angular momentum=nh2π                                     nh2π=3h2π                                  therefore n = 3,orbital angular momentum =ℓ(ℓ+1)h2πℓ(ℓ+1)h2π=32hπ ℓ(ℓ+1)2=32ℓ(ℓ+1)=6 l = 2Number of radial nodes = n - l -1                                 = 3 - 2 - 1                                 = 0Number of angular nodes = l = 2
