The number of radial nodes of 3 ~s and 2 p orbitals respectively are

Options

  1. A0,2
  2. B2,0
  3. C1,2
  4. D2,1

Correct answer

B. 2,0

Step-by-step solution

Number of spherical/radial nodes in any orbital =n-I-1 For s= orbitals, I=0 . Number of radial nodes in 3s-orbital =3-0-1=2 For p - orbitals, I=1 Number of radial nodes in 2 p -orbitals =2-1-1=0
