The number of angular nodes and radial nodes in 3 s orbital are

Options

  1. A0 and 2 , respectively
  2. B1 and 0 , respectively
  3. C3 and 0 , respectively
  4. D0 and 1 , respectively

Correct answer

A. 0 and 2 , respectively

Step-by-step solution

No. of angular nodes = ℓ No. of Radial nodes = n - ℓ - 1 For 3 s ;   n = 3 and ℓ = 0 ∴ No. of angular nodes = 0 ∴ No. of radial nodes = 2
