Question

Consider the following statements:

(A) The principal quantum number '' is a positive integer with values 
(B) The azimuthal quantum number '' for a given '' (principal quantum number) can have values  and has  values.
(C) Magnetic orbital quantum number '' for a particular '' (azimuthal quantum number) has  values.
(D)  are the two possible orientations of electron spin.
(E) For , there will be a total of 9 orbitals.

Which of the above statements are correct?

Canvas Classes · Accepted Answer

Evaluate each:

(A) ✓  — correct definition.

(B) ✗  ranges from  to  (not ), giving  values (not ).

(C) ✓  ranges from  to , giving  values.

(D) ✓  — correct.

(E) ✗ For :  has  values → 11 orbitals, not 9.

Correct: (A), (C), (D) → Answer: Option (3)
