Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Noble gases have a stable electron configuration with a full outermost energy level, which makes them very unreactive. This means that they do not easily form compounds with other elements. They have low boiling and melting points, and are colorless and odorless gases at room temperature. Additionally, noble gases have high ionization energies, which means it requires a large amount of energy to remove an electron from their outermost energy level.
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
No. Chlorine's electron configuration is unstable. As a result, chlorine is a highly reactive element.
Cl-1.
In order for an atom to be chemically stable it must have 8 valence electrons.
it all depends on the electron configuration if it is positive or negative, you have to look at the transition metals and valence electrons and determine the charge and use the formula n-11s^2 2s^2 2p^6 3s^2 3p^6 3d^10
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
They achieve stable configuration by sharing their electrons in their outermost shell.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
A stable electron configuration.

By acquiring noble gas configuration elements become stable .
