Two electrons.
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.

Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.

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.

Magnesium has two electrons in its outermost shell.
2 Because Magnesium only has 2 electrons in it's outer shell
it needs six more electrons to have a full outer valence shell.
If you are talking about the electronic structure, which is 2.8.2. This would therefore mean that there are 2 electrons in the outer shell of magnesium.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
