11 Na =1 s2, 2 s2, 2 p6, 3 s1 For 3 s1, n=3, l=0, m=0, s=(1/2)

Q. The correct set of four quantum numbers for the outermost electron of sodium ( $Z = 11$ ) is

$3, 1, 0, \frac{1}{2}$

$3, 1, 1, \frac{1}{2}$

$3, 2, 1, \frac{1}{2}$

$3, 0, 0, \frac{1}{2}$

$_{11} N a = 1 s^{2}, 2 s^{2}, 2 p^{6}, 3 s^{1}$

For $3 s^{1}$ ,

$n = 3,$

$l = 0,$

$m = 0,$

$s = \frac{1}{2}$
