B)two

D)twelve

Question

Quizplus · Accepted Answer

Ions are formed when the atoms gain or lose electrons to achieve a stable electron configuration. The stable electron configuration is achieved by having a full outermost shell of electrons, which is characteristic of a noble gas. Noble gases have eight valence electrons (except for helium, which has two), so generally, ions end up with a stable, noble-gas configuration having eight electrons in their outermost shell. This is known as the octet rule. Therefore, the best choice is option C, which states that ions end up with eight electrons in their outermost shell.
