Question

Quizplus · Accepted Answer

Magnesium has two valence electrons and tends to lose them to achieve a stable noble gas electron configuration. By losing two electrons, it becomes positively charged and forms an ion. The most stable ion of magnesium is the one with a 2+ charge, which is formed by losing its two valence electrons. Therefore, the correct answer is E) 2+.
