Which of the following statements are true? (A) The subsidiary quantum number l describes the shape of the orbital occupied by the electron. (B) is the boundary surface diagram of the 2 p_x orbital. (C) The + and - signs in the wave function of the 2 p _ x orbital refer to charge. (D) The wave function of 2 p_x orbital is zero everywhere in the xy plane.

Options

  1. A(B) and (D) only
  2. B(A), (B) and (C) only
  3. C(C) and (D) only
  4. D(A) and (B) only

Correct answer

D. (A) and (B) only

Step-by-step solution

(A) Azimuthal quantum number ( ) indicates the shape of orbital occupied by the electron (B) p _ x orbital (C) The + and - sign in the wave function of 2 p_x orbital refer to the sign (Phase) of the wave function, not the charge (D) The wave function of 2 p_x orbital will be zero in yz plane (Nodal plane).
