8 electrons are needed in the outer level to become a stable element.
Writing A Bohr Atomic Model (LEVELS):
- 1st level- Up to 2 electrons
- 2nd level- Maximum of 8 electrons
- 3rd level- 18, 8, or less electrons
- 4th-7th level- 32, 18, 8, or less electrons

What is the process of losing or gaining electrons to become stable?
The process of losing or gaining electrons to become stable is called ionization.
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.
When an element gives an electron to another element is called?
This is usually part of the bonding process called ionic bonding.
How many electrons does barium lose to become a stable octect?
Two electrons.
Do Eletrically neutral element have equal numbers of electrons and neutrons?
Electrically neutral elements have equal numbers of electrons and protons. A stable element has equal numbers of protons and neutrons. Thus, the answer to the question ''Do Eletrically neutral element have equal numbers of electrons and neutrons?'' depends on the stability of the element i.e. if stable then yes and if unstable than might not.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
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.
If all element had atoms with a stable number of electrons what effect would this have a chemical reaction?
Chemical Reactions would not exist, since unstable electrons are needed to start a Chemical Reaction, All the molecules would be stable, so they would not need to undergo change to become more stable.
When an element has the same number of protons and electrons the element is a?
the element is stable.
What does and element's oxidation number indicate?
An element's oxidation number indicates how many electrons an atom has gained, lost, or shared to become stable.
How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
When is an element stable?
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
How many electrons does sulfur gain or lose to become stable?
Sulfur gains 2 electrons to become stable.
Is the krypton element stable or unstable?
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
What is the process of losing or gaining electrons to become stable?
The process of losing or gaining electrons to become stable is called ionization.
What element is stable with 2 valence electrons?
calcium
