How many electrons will magnesium gain or lose?

What is the number of electrons gained or lost in magnesium?

How does magnesium achieve a stable outermost energy level?

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Explanation: Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge.

Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).

four electrons
Group IV A atoms have four valence electrons to be stable these atoms can lose four or gain four electrons to achieve stability. Losing 2 electrons can create a filled s subshell.

2 Answers. The magnesium ion Mg2+ is formed when the magnesium atom loses the two electrons from its outer shell! to form a stable ion with a noble gas configuration.

Magnesium has a total of 12 electrons – 2 in the innermost shell, 8 in the second shell, and two electrons in its valence shell (third shell). Magnesium acquires a full octet by losing 2 electrons and emptying out its outermost shell.
