8 electrons
Stable.
These are the "noble gases." They are chemically inert, because they have a full octet of electrons in their valence energy level. Therefore, they do not need to lose or gain electrons to achieve stability; rather, they are naturally stable, which is why they do not react.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Both atoms usually attain the stable highest energy level configuration of a noble gas. This occurs through the sharing, gaining, or losing of electrons to achieve a full outer electron shell, which is the most stable configuration.
The electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration.
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
yes
Neon's complete electron configuration is: 1s22s22p6 Therefore, normally, neon does not have any electrons in its third energy level. As you can see, neon is a noble gas with 8 electrons in its valance shell, and is therefore chemically stable and is unlikely to react.
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
filled with electrons
Stable.
They share their valence electrons
The most stable atoms/ions have 8 electrons in their outermost shell.
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
Most atoms are stable when they have a full outer energy level, which typically consists of 8 electrons. This is known as the octet rule. However, some smaller atoms, such as hydrogen and helium, are stable with only 2 electrons in their outer energy level.
These are the "noble gases." They are chemically inert, because they have a full octet of electrons in their valence energy level. Therefore, they do not need to lose or gain electrons to achieve stability; rather, they are naturally stable, which is why they do not react.
