Structure of Atom · Quantum numbers

Given,

(A) $n = 5$ , $m_l = -1$

(B) $n = 3$ , $l = 2$ , $m_l = -1$ , $m_s = +\dfrac{1}{2}$

The maximum number of electron(s) in an atom that can have the quantum numbers as given in (A) and (B) respectively are :

We corrected a printing error in the original paper

Source printed the magnetic quantum number as “m $_1$ ” and the azimuthal quantum number in (B) as “1 = 2” (digit 1 for l).
