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.
Why does Mg have a charge of 0?
Magnesium, Mgstart text, M, g, end text, is a group 2 element that will form 2+ cations. Because it usually forms cations of only one type, we don't need to specify its 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.

What is the Mg ion?
Magnesium ions (Mg2+) are the most abundant divalent metal ions within cells. They bind to a number of proteins and nucleic acids, regulating a wide range of biological processes such as ATP utilization, enzyme activation, and maintenance of genomic stability (Hartwig, 2001; Cowan, 2002).
