A ground state sodium atom has one valence electron.

Which set of quantum numbers describes this electron?

$n = 1$$l = 0$${m}_{l} = 0$${m}_{s} = \frac{1}{2}$

$n = 2$$l = 1$${m}_{l} = 0$${m}_{s} = -\frac{1}{2}$

$n = 2$$l = 0$${m}_{l} = 0$${m}_{s} = -\frac{1}{2}$

$n = 3$$l = 0$${m}_{l} = 0$${m}_{s} = \frac{1}{2}$

$n = 3$$l = 1$${m}_{l} = 0$${m}_{s} = \frac{1}{2}$
