What is Magnesium's charge when it has a complete set of valence electrons?
Wiki User
∙ 14y ago
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.

∙ 13y agoBecause Oxygen needs to more electrons to become stable (Neon), it has a charge of 2-.
Example: Aluminum-
It has 13 electrons and needs to get to the closest Noble Gas. The closest Noble Gas is Neon (10 electrons). So aluminum's charge is 3+, because it has three extra electrons than the stable state.
I hope this answered your question

What is the charge of valence electrons of calcium?
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
How is the number of valence electrons of a nonmetal related to the charge on the ion the nonmetal?
Nonmetals will undergo chemical reactions that result in a stable electron configuration of 8 electrons in the outer shell. The number of valence electrons tells you have many they have in their outer shell prior to any chemical reaction, and therefore, how many more electrons they need to get a complete set of 8. So for example, oxygen has 6 valence electrons and therefore needs 2 more to have 8, so it will form an ion with a charge of minus two, which is the charge that is carried by the additional two electrons that oxygen will acquire. Chlorine has 7 valence electrons, therefore it needs just one more electron to complete its outer shell, and as an ion will have a charge of minus one. Nitrogen has 5 valence electrons, so it needs 3 more, and will form an ion with a charge of minus three.
What charge would nitrogen have if it gained 3 electrons?
Nitrogen would have a neutral charge and eight valence electrons.
How do you figure out the core charge of an atom?
the atomic core charge of an atom is the same as the number of valence electrons in the atom
How many electrons are in a phosphorus Ion's outermost energy level?
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
What is the charge of valence electrons of calcium?
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
How does an atom keep its charge?
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.

What is formal charge?
Formal charge is used when creating the Lewis structure of a molecule, to determine the charge of a covalent bond. Formal charge is the difference between the valence electrons, unbound valence electrons, and half the shared electrons.
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
valence electron in nitrogen
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
What charge would nitrogen have if it gained 3 electrons?
Nitrogen would have a neutral charge and eight valence electrons.
Which electrons have the most energy in an atom?
All electrons in an atom have: * a negative one charge * 1/2 spin * 0.511 MeV of mass
How do you figure out the core charge of an atom?
the atomic core charge of an atom is the same as the number of valence electrons in the atom
How many valence electrons does Chlorine have with a negative charge?
There are seven.
Why are non valence electrons not involved in reactions?
they have no charge and are inert
Do valence electrons carry an electrical charge?
Yes, electrons must balance out with the protons, so all electrons must carry a negative charge.
