There are 2 outer shell electrons in Magnesium.
Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Magnesium has 2 electrons on its outer energy level.
Atoms with fewer than 8 valence electrons can fill their outermost energy level by forming chemical bonds with other atoms. For example, magnesium can lose 2 electrons to achieve a full outer energy level, becoming a +2 cation. Conversely, sulfur can gain 2 electrons to fill its outer energy level, becoming a -2 anion. Both processes result in stable, filled outer energy levels for the atoms involved.
Uranium has 2 electrons on its outer energy level.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.

Magnesium has 2 electrons on its outer energy level.
There are 2 electrons in the valence orbital of a Magnesium atom.
Atoms with fewer than 8 valence electrons can fill their outermost energy level by forming chemical bonds with other atoms. For example, magnesium can lose 2 electrons to achieve a full outer energy level, becoming a +2 cation. Conversely, sulfur can gain 2 electrons to fill its outer energy level, becoming a -2 anion. Both processes result in stable, filled outer energy levels for the atoms involved.
The outermost electrons, found in the highest energy level, are the most likely to be lost in a magnesium atom. Magnesium has 2 electrons in its outermost energy level, so it tends to lose these electrons to achieve a stable electron configuration.
Uranium has 2 electrons on its outer energy level.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
Vanadium has 5 electrons in its outer energy level.
When magnesium becomes an ion, it loses its two valence electrons from its outermost energy level. This loss of electrons results in the formation of a positively charged ion, specifically a magnesium cation (Mg²⁺). Consequently, the charge of the magnesium ion is +2, as it has two more protons than electrons.
Iodine has 7 electrons in its outer energy level.
There are 8 electrons in the outer energy level of xenon. Xenon belongs to the noble gas group on the periodic table, which have a full outer energy level with 8 electrons.
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
