A neutral magnesium atom has 12 protons ans 12 electrons.
Mg squared?
Do you mean Mg2+
===========
12 electrons 12 protons and 12 neutrons
12 electrons.

If there are excess electrons in an atom, the atom is likely to be ionized; that is, the stom will emit the electrons.
To make the atom equal you get another atom that has the amount you need to make 8 on the Bohr model, for instance Mg (Magnesium) and O (oxygen) Mg has two electrons on the outer shell/ring and oxygen has 6 electrons, to make it equal you would either add two Mg to O or you could add six O to Mg, then it would be written like Mg ^2+ + O^2- --> MgO
A fluorine atom has 9 electrons.
5 valence electrons
there are four valence electrons in tin/

Magnesium is a metal element. There are 12 electrons in a single atom.
Mg has 2 valence electrons.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
Magnersium is a non metal element. There are 12 electrons in a single atom.
Mg always has 2 valence electrons

It an atom has 12 electrons and is neutral, then it must be Mg (magnesium), and magnesium has 2 valence electrons which would be used in bonding.
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.
12The atomic number of Mg is 12. This means it has 12 protons in the nuclei of its atoms. In a neutral atom, the number of electrons equals the number of protons.12
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
