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.
A magnesium (Mg) atom loses two electrons to form a magnesium cation (Mg²⁺). This occurs because magnesium has two electrons in its outermost shell, and it tends to lose these electrons to achieve a stable electron configuration similar to that of the nearest noble gas, neon. As a result, Mg²⁺ has a positive charge of +2.
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.
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.
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).
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.
