Consider the following statements :
(A) The principal quantum number ‘n’ is a positive integer with values of ‘n’ = 1, 2, 3, ….
(B) The azimuthal quantum number ' $\ell$ ' for a given ‘n’ (principal quantum number) can have values as ' $\ell$ ' = 0, 1, 2, …. n
(C) Magnetic orbital quantum number ' $\mathrm{m}_{\ell}^{\prime}$ for a particular ' $\ell$ ' azimuthal quantum number) has $(2 \ell+1)$ values.
(D) ±1/2 are the two possible orientations of electron spin.
(E) For $\ell$ = 5, there will be a total of 9 orbital.
Which of the above statements are correct?
