mg+2
The chemical symbol for a magnesium atom that has lost two electrons is Mg2+.
Mg is the symbol for the element magnesium and could be used to represent a neutral atom of magnesium. Mg2- does not occur, but Mg2+ does, and is the symbol of a magnesium ion, which is a magnesium atom that has lost two electrons.
The chemical symbol of uranium is 'U' and it has 92 electrons.
Neutral atom of magnesium has 12 electrons.
Loses two electrons.
Magnesium is a metal element. There are 12 electrons in a single atom.

The chemical symbol of uranium is 'U' and it has 92 electrons.
Neutral atom of magnesium has 12 electrons.
The chemical symbol of uranium is U. Uranium has 92 electrons.
The chemical symbol of chlorine is Cl. Atomic number of it is 17. It has 17 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Loses two electrons.
There are 2 electrons in the valence orbital of a Magnesium atom.
Some or all of its valence electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The element magnesium has the atomic number 12, and it will have 12 protons in its nucleus. The neutral atom will have 12 electrons around it. Note that magnesium will loan out electrons to form chemical bonds, and it may be short a couple. Magnesium (Mg) has 2 electrons in its outer (valence) electron shell. That places this Alkaline Earth metal in Group 2 of the Periodic Table. When magnesium reacts, it loans out those two electrons to become an ion, Mg++. In this case, it will have 10 electrons.
Magnesium is a metal element. There are 12 electrons in a single atom.
