Explanation:

It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.

                    n = l + 1

where,     n = principle quantum number  

                l = azimuthal quantum number

Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l is 0 for s, 1 for p, 2 for d, 3 for f, and so on.

Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.

  • Electronic configuration of Rb is [tex][Kr] 5s^{1} [/tex]. So here, n = 5, l = 0, m = 0 and s = ± [tex]\frac{1}{2}[/tex].
  • Electronic configuration of [tex]S^{2-}[/tex] is [tex][Ne]3s^{2}3p^{6}[/tex]. So here, n = 3, l = 1, m = -1, 0, +1, and s = ± [tex]\frac{1}{2}[/tex].
  • Electronic configuration of [tex]Ag^{+}[/tex] is [tex][Kr]4d^{10}[/tex]. So here, n = 4, l = 2, m = -2,  -1, 0, +1, +2 and s = ± [tex]\frac{1}{2}[/tex].
  • Electronic configuration of F is [tex]1s^{2}2s^{2}2p^{5}[/tex]. So here, n = 2, l = 1, m = -1, 0, +1, and s = ± [tex]\frac{1}{2}[/tex].
