The number of radial nodes, angular nodes of a 4 f - orbital are respectively
Options
- A0 , 3
- B1 , 2
- C2 , 1
- D2 , 0
Correct answer
A. 0 , 3
Step-by-step solution
Radial nodes are the spherical surface region where the probability of finding an electron is zero. It depends on both the values of the principal quantum number and the azimuthal quantum number. The number of nodes of particular orbital an increases with increase in their principal quantum number. Angular nodes = l For 4 f -orbital, l = 3 Radial nodes = n - l - 1 Radial nodes = 4 - 3 - 1 = 0 Hence, the number of angular and radial nodes of 4 f -orbitals are 3 and 0 respectively.
