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

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

Answer

Brief Explanations:

Magnesium is in Group 2 of the periodic table and has 2 valence - electrons. To satisfy the octet rule (have 8 electrons in its outer shell), it is easier for magnesium to lose its 2 valence - electrons rather than gain electrons. Gaining 6 or 8 electrons is energetically unfavorable, and losing 4 electrons is also not likely as it would require breaking into a lower energy shell.

Answer:

by losing two electrons
