Few statements are given regarding nodes in the orbitals. Mark the statement which is not correct.
A
In case of 
- orbital, xy plane is a nodal plane.
- orbital, xy plane is a nodal plane.
B
ns- orbital has (n+1) nodes.
C
The number of angular nodes is given by l.
D
The total number of nodes is given by (n -1) i.e., sum of l angular nodes and (n – l – 1 )radial nodes.
Text Solution
Verified by ExpertsThe correct answer is:
B
In case of 
orbital, lobes are along z - axis and thus 
plane is a nodal plane.
For, ns - orbital total number of nodes 
where angular nodes 
and number of radial nodes 
Thus, the total number of nodes is given =angular nodes + radial nodes
