How many radial nodes are present in 4d-orbital ?

How many radial nodes are present in 4d and 5f orbitals?radial nodes = n – l – 1 (where n is the principal quantum number and l is the azimuthal quantum number). Here, n = 4 and l = 2. Therefore, the total number of radial nodes in the orbital = 4 – 2 – 1 = 1. Therefore, the 4d orbital contains only 1 radial node.
