There are 2 electrons in the valence orbital of a Magnesium atom.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.

In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit
Sodium has 8 electrons in the n=2 orbit. This is because the second energy level (n=2) can hold up to 8 electrons max. Sodium has 11 electrons in total, with 3 in the n=1 orbit and 8 in the n=2 orbit.
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.

Magnesium has 3 electron orbits. The first orbit can hold up to 2 electrons, the second orbit can hold up to 8 electrons, and the third orbit can hold up to 8 electrons.

Oxygen have 6 electrons on the outer sell so it need 2 more electrons to gain full outer shell. Magnesium have 2 electrons on the outer sell so It have to lose 2 electrons to gain full outer sell. They combine easily by a strong ionic bond. Its formula is MgO, it has no overall charge.
In MgCl², Magnesium has 12 electrons, and its electronic configuration can be written as 2,8,2. Thus Magnesium has two electrons in its outermost orbit or it can be said that Magnesium has 2 valence electrons.In MgCl², each Chlorine atom has 17 electrons and its electronic configuration can be written as 2,8,7. Thus each Chlorine atom has seven electrons in its outermost orbit or it can be said that each Chlorine has 7 valence electrons.Magnesium wants to give away its two valence electrons to complete its octet by having 8 electrons in its outermost orbit attaining the electronic configuration of its nearest inert gas Neon. And each chlorine atom wants to complete its octet by adding one more electron in its outermost orbit so that it can have 8 electrons in its outermost orbit attaining the electronic configuration of its nearest inert gas Argon. So, we see that Magnesium wants to lose two electrons and each Chlorine atom wants to add one more electron in their outermost orbit Thus, Magnesium transfers its two electrons to two Chlorine atoms (one electron to each Chlorine atom) and thus Magnesium obtains +2 charge and each chlorine atom acquires −1 charge and ionic bonds are formed between the atoms of the molecule.An eletrovalent compound or ionic compound is formed when one atom in the compound transfers its electrons from itself to its neighboring atom. In MgCl², Magnesium transfers its two electrons to its neighboring chlorine atoms, and forms two ionic bonds between the atoms. Thus, MgCl² is an electrovalent compound or an ionic compound.
A neutral atom of oxygen has 6 electrons in it's most outer orbit. Generally, if you count horizontally from left-to-right on the periodic table, you get the number of electrons in its' most outer orbit. You start every row with 1, of course. :) Hope that helps!

Berilium, Magnesium, Calcium, Strontium, Barium and Radium
Oxygen has 6 valence electrons. These are in the outer orbit.
The number of protons is usually the same as the number of electrons!:)
