Answer is 1,0
For 2s Orbital,
n=2 , l=0
1) Spherical nodes of 2s orbital is given by formula:
n-l-1
                                   Â
n=2 l=0 for 2s Orbital
                                  Â
= 2-0-1
                                 Â
= 1
Spherical nodes for 2s orbital is 1
2) Calculation of angular nodes for 2s
orbital:
Angular nodes for 2s orbital=l
FOR 2S orbital l=0
there fore angular nodes for 2s orbital is
0
