A neutral magnesium atom has 12 protons ans 12 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.
A carbon-12 atom has 6 electrons. The atomic number of carbon is 6, which determines the number of electrons in a neutral carbon atom.
An atom of Sn (Tin) has 4 valence electrons in the 5th shell, so it has 4 p electrons.
Sulfur-33 has 16 electrons since it is a neutral atom and the number of electrons is equal to the number of protons in the nucleus for a neutral atom.

Magnesium is a metal element. There are 12 electrons in a single atom.
Mg has 2 valence electrons.
Magnersium is a non metal element. There are 12 electrons in a single atom.
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.

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.
Atom Mg-26 in the ground state has 2 valence electrons. Magnesium (Mg) has an atomic number of 12, so it has 12 electrons in total. In the ground state, the electron configuration is [Ne] 3s2, which means it has 2 electrons in the outermost shell (valence electrons).
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
A Mg atom has an equal number of protons and electrons, resulting in a neutral charge, while a Mg^2+ ion has lost two electrons, giving it a positive charge. This difference in electron configuration affects the reactivity and chemical properties of each.
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.
