The most common magnesium ion is Mg2+. It loses 2 electrons. By losing 2 electrons, Mg then has no electrons in the 3s energy level, drastically reducing the energy of the atom.
The periodic table states that the atomic number of magnesium is 12. A magnesium atom would thus have 12 protons in its nucleus; any atom that has 12 protons must be a magnesium atom. Atomic number = number of protons

Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
Magnesium has 2 electrons on its outer energy level.
An atom of magnesium has 2 valence electrons. Magnesium is in group 2 of the periodic table, so it has 2 electrons in its outer shell.
The atomic number of magnesium is 12. The cation loses two electrons for 10.
Magnesium cation has a 2+ charge (Mg2+). The meaning is two electrons minus.
Magnesium has 12 electrons, with 2 electrons in its outermost shell. To have a full octet, magnesium needs to lose these 2 electrons to achieve a stable electron configuration, resulting in a 2+ charge as it becomes a cation.
Magnesium typically loses two electrons to achieve a stable electron configuration, forming a cation. As a result, the charge on the magnesium ion is +2, represented as Mg²⁺. This loss of electrons occurs because magnesium is an alkaline earth metal, which tends to lose electrons readily during chemical reactions.
When an atom loses an electron, it becomes positive (Since you're taking away something that is negative). It would not become an ion, it would become a cation.
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?

18 electrons.
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
Magnesium and the rest of the alkaline earth metals have two valence electrons.
The number of electrons is 10.
