Magnesium acts similar to sodium when forming an ionic bond in terms of losing or gaining electrons. What is the most likely way in which an atom of magnesium (Mg) will satisfy the octet rule when it forms bonds?

Magnesium has two electrons in its outer shell. It most readily satisfies the octet rule by losing those two electrons, leaving a full outer shell beneath them and forming Mg²⁺. Thus, the correct choice is by losing two electrons.
