Question

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? by losing two electrons by losing four electrons by gaining six electrons by gaining eight electrons

Explanation:

Magnesium has an atomic number of 12 and an electron - configuration of 2, 8, 2. To satisfy the octet rule by having 8 electrons in its outer shell, it is more energetically favorable to lose its 2 outer - shell electrons rather than gain electrons.

Answer:

A. by losing two electrons
