Radial nodes present in 3s and 2p-orbitals are respectively

Options

  1. A0, 2
  2. B2, 0
  3. C2, 1
  4. D1, 2

Correct answer

B. 2, 0

Step-by-step solution

Number of radial nodes = ( n - l - 1 ) For 3s, n = 3 , l = 0 (Number of radial node = 3 - 0 - 1 = 2 ) For 2p, n = 2 , l = 1 Number of radial node = 2 - 1 - 1 = 0
