Why does Mg have a 2+ charge?
Because the outer electron shell of a magnesium atom has two electrons in it. Both are lost when it changes to an ion leaving it with 12 positively charged protons and 10 negatively charged electrons. This produces a +2 positive charge.
Is Mg a positively charged ion?
Thus, whenever it loses these electrons, it becomes a positively charged ion. So, it is true that a magnesium ion has a net positive charge while the magnesium atom has no charge.
Is Mg positive or negative?
The formula for lithium bromide is LiBr. When an ionic compound is formed from magnesium and oxygen, the magnesium ion has a 2+ charge, and the oxygen atom has a 2− charge….Recognizing Ionic Compounds.

Is magnesium a negative charge?
A magnesium ion has a net positive charge while the magnesium atom has no charge.

Does magnesium have a charge?
Magnesium has two electrons in its outer shell as it is in group 2 of the periodic table, which it loses, so its outer shell is full (2,8) and it has a charge of +2, as it still has 12 protons (positive charges) and now has only 10 electrons (negative charges).
