I hope this helps
A. it has 11 electrons.
b. the elctron configuration is 2,8,1
c. when sodium ionizes it loses 1 electron because it is easier to lose 1 rather than gain 7. hope it was helpful.
X=375 because everything is multiplied by 15, y=15x, and 375*15=5625.
Y=6300 for the same reasoning: 420*15=6300
<u>so the answer is C</u>
(12 + 6) / (3 + 3) =
18 / 6 =
3
ur answer is : (12 + 6) / (3 + 3)
