Use the octet rule to explain why metals and nonmetals typically form oppositely charged ions. Explain how we would use the octet rule to predict the charge of a potassium ion and a sulfide ion. (Lesson 5) Atoms will gain or lose electrons to obtain 8 electrons in it outer shell. Atoms do this because they want to reach an electron configuration of the nearest noble gas. So in the case of a potassium ion and a sulfide ion potassium would lose one valance electron in the outer most layer to achieve the octet rule. While sulfide would gain two valance electron to achieve the octet rule. Thus resulting in +1 charge for potassium and a -2 charge for sulfide. A compound is found to contain 49.5% carbon, 5.19% hydrogen, 16.5% oxygen, and 28.9% nitrogen.
