A neutral atom of magnesiumhas two electronsin its outermost energy level
There are 2 electrons in the valence orbital of a Magnesium atom.
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.
There are 8 electrons in the outermost energy level of a chloride ion (Cl-) in table salt. This is because chlorine has 7 electrons in its neutral state, and when it gains an electron to become Cl-, it has a full outer shell with 8 electrons.
Bromine has 7 electrons in its outermost energy level.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons

A neutral sulfur atom has 6 electrons in its outermost energy level. Sulfur has 16 electrons, with 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third and outermost energy level.
There are 2 electrons in the valence orbital of a Magnesium atom.
An example is magnesium.
Mg -magnesium.
A neutral atom with an atomic number of 15 (phosphorus) will have 5 electrons in its outermost energy level. This is because the atomic number tells us the number of protons, which is equal to the number of electrons in a neutral atom. The outermost energy level for phosphorus is the third energy level.
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.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Magnesium is in group 2 of the Periodic table, and so has 2 electrons in its outermost energy level. Therefore, its outermost energy level is full once 2 electrons are removed, and so it has an ionisation number of 2
The neutral atom of phosphorus has 15 electrons.
The element with 2 valence electrons on the third energy level is magnesium. Magnesium has an electron configuration of 2-8-2, with 2 electrons on the outermost energy level.
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
