Radial nodes and planar nodes

Nodes:

Total number of nodes = (n - 1)

Radial node is a spherical surface where the probability of finding an electron is zero. The number of radial nodes increases with the principle quantum number (n).

No. of radial nodes = (n- l- 1)

where n is the principal quantum number, l is the azimuthal quantum number. 

Angular node is also called nodal plane. Angular node is a plane that passes through the nucleus. Angular node is equal to the azimuthal quantum number (l).

no. of planar nodes = l

where l is the azimuthal quantum number.
