Calculate the total number of angular and radial nodes present in 3d a

1.	Calculate the total number of angular and radial nodes present in 3d and 4f Orbitals.Calcium Hydroxide cannot be used to remove permanent hardness of water. why?
Answer» Concepts :- angular nodes = l radial nodes = n - l - 1 where n is principle quantum number l is azimuthal quantum number. in case of 3d , n = 3 and l = 2 so, angular nodes = 2 radial nodes = 3 - 2 - 1 = 0 in case of 4f , n = 4 and l = 3 so, angular nodes = 3 radial nodes = n - l - 1 = 4 - 3 - 1 = 0

Answer»

Concepts :- angular nodes = l radial nodes = n - l - 1 where n is principle quantum number l is azimuthal quantum number.

in case of 3d , n = 3 and l = 2 so, angular nodes = 2 radial nodes = 3 - 2 - 1 = 0

in case of 4f , n = 4 and l = 3 so, angular nodes = 3 radial nodes = n - l - 1 = 4 - 3 - 1 = 0
