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 $2 \mathrm{p}_{\mathrm{x}}$ orbital refer to charge. (D) The wave function of $2 p_x$ orbital is zero everywhere in the xy plane.
(B) and (D) only
(A), (B) and (C) only
(C) and (D) only
(A) and (B) only
Solution
(A) Azimuthal quantum number $(\ell)$ indicates the shape of orbital occupied by the electron (B) $\mathrm{p}_{\mathrm{x}}$ 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).
