∙ 9y agoA neutral atom is said to stable. Therefore in an electrically neutral atom the number of electrons (e-) will equal the amount of protons (p+).
Wiki User
∙ 15y agoThe same number of electrons as there are protons in the nucleus.

∙ 14y agoatomic stability depends on the number of protons and neutrons in the nucleus not the electrons. highly charged ions a. f. i. C^(6+) are stable.

∙ 13y agoThe amount of electrons needed to make an element stable is the amount of electrons needed in order to make a complete outer (valence) shell.

How many electrons does sulfur gain or lose to become stable?
Sulfur gains 2 electrons to become stable.
How many electrons do the elements of the most stable group have in their outer shells?
Most of the noble gases have 8 electrons in their outer shell, but helium has only 2, and is the most stable of all elements.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
How many electrons does sulfur gain or lose to become stable?
Sulfur gains 2 electrons to become stable.
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
How many electrons are in a complete octet why is having a complete octet important?
eight. it is important to obtain octet so that elements become stable.
How many electrons does barium lose to become a stable octect?
Two electrons.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
How many electrons do the elements of the most stable group have in their outer shells?
Most of the noble gases have 8 electrons in their outer shell, but helium has only 2, and is the most stable of all elements.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
Why does an element gain or lose electrons to become an ion?
When elements react with other elements, they gain or loose electrons. Electrons are the reason that some elements react and others do not. Each element wants to have eight outer electrons. This is called the octet rule. (oct means eight). However, most elements do not have eight (except for the elements in the 18th column of the periodic table). The periodic table shows how many electrons each element has on its outer-layer. The last number of the column # (in the periodic table) is the number of electrons that the element contains in its outer-ring. For example, elements in the first column have one. Another way is when substances burn and reach oxygen. This is called oxidation reaction.
How many electrons do barium need to lose to become stable?

How many electrons does a magnesium atom need to lose to become stable?
2
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
