Question

Consider the following statements :

(A) The principal quantum number ' $n$ ' is a positive integer with values of ' $n$ ' $= 1, 2, 3, \dots$

(B) The azimuthal quantum number ' $l$ ' for a given ' $n$ ' (principal quantum number) can have values as ' $l$ ' $= 0, 1, 2, \dots . n$ has $(2 n + 1)$ values.

(C) Magnetic orbital quantum number ' $m$ ' for a particular ' $l$ ' (azimuthal quantum number) has $(2 l + 1)$ values.

(D) $\pm \frac{1}{2}$ are the two possible orientations of electron spin.

(E) For $l = 5$ , there will be a total of $9$ orbital
