The equation for the formation of a magnesium ion from a magnesium atom involves the loss of two electrons. It can be written as:
Mg (s) -> Mg2+ (aq) + 2e-
Magnesium is an atom; but this atom can be transformed in an electrically charged atom - called cation, Mg2+.
Loses two electrons.
When a magnesium atom becomes a magnesium ion, it loses two electrons from its outermost shell, resulting in a positively charged ion (Mg²⁺). This change in electron structure transforms the neutral magnesium atom, which has 12 electrons, into an ion with only 10 electrons. Consequently, the ion achieves a stable electron configuration similar to that of neon, with a full outer shell.
When a neutral magnesium atom loses two electrons, it becomes a magnesium ion (Mg²⁺). Since electrons carry a negative charge, losing two electrons results in a net positive charge of +2 on the magnesium ion. Therefore, the net electrical charge on a magnesium ion is +2.
The neutral atom of magnesium has no electrical charge; the ion is bivalent.

A magnesium ion differs from a magnesium atom because it has two fewer electrons. When a magnesium atom loses two electrons, it forms a magnesium ion with a 2+ charge.
The formula for a magnesium ion is Mg2+. This indicates that the magnesium atom has lost two electrons, giving it a positive charge of 2.
When a neutral magnesium atom loses two electrons, it becomes a magnesium ion (Mg²⁺). Since electrons carry a negative charge, losing two electrons results in a net positive charge of +2 on the magnesium ion. Therefore, the net electrical charge on a magnesium ion is +2.
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
A magnesium atom will lose two electrons to achieve a stable octet configuration, forming a Mg2+ ion. A chlorine atom will gain one electron to achieve a stable octet configuration, forming a Cl- ion. When magnesium and chlorine react, magnesium will transfer electrons to chlorine, resulting in the formation of the ionic compound magnesium chloride.
When a magnesium atom loses an electron from its outer energy shell, it forms a positively charged magnesium ion (Mg2+). This ion has a stable electron configuration by achieving a full outer energy level, which is characteristic of noble gases. Magnesium usually loses its two outermost electrons to form this stable ion.
